Rust (...and also +the fastest).

This is for you! +* **Pluggable Compilers**: you want to emit code with DynASM or other compiler? We got you! +* **Headless mode**: that means that no compilers will be required + to run a `serialized` Module (via `Module::deserialize()`). +* **Cross-compilation**: You can pre-compile a module and serialize it + to then run it in other platform (via `Module::serialize()`). + +## Config flags + +Wasmer has the following configuration flags: +* `wat` (enabled by default): It allows to read WebAssembly files in their text format. + *This feature is normally used only in development environments* +* Compilers (mutually exclusive): + - `singlepass`: it will use `wasmer-compiler-singlepass` as the default + compiler (ideal for **blockchains**). + - `cranelift`: it will use `wasmer-compiler-cranelift` as the default + compiler (ideal for **development**). + - `llvm`: it will use `wasmer-compiler-llvm` as the default + compiler (ideal for **production**). + +Wasmer ships by default with the `cranelift` compiler as its great for development proposes. +However, we strongly encourage to use the `llvm` backend in production as it performs +about 50% faster, achieving near-native speeds. + +> Note: if you want to use multiple compilers at the same time, it's also possible! +> You will need to import them directly via each of the compiler crates. + +--- + +Made with ❤️ by the Wasmer team, for the community diff --git a/lib/js-api/src/env.rs b/lib/js-api/src/env.rs new file mode 100644 index 00000000000..d8078414579 --- /dev/null +++ b/lib/js-api/src/env.rs @@ -0,0 +1,224 @@ +use crate::{ExportError, Instance}; +use thiserror::Error; + +/// An error while initializing the user supplied host env with the `WasmerEnv` trait. +#[derive(Error, Debug)] +#[error("Host env initialization error: {0}")] +pub enum HostEnvInitError { + /// An error occurred when accessing an export + Export(ExportError), +} + +impl From for HostEnvInitError { + fn from(other: ExportError) -> Self { + Self::Export(other) + } +} + +/// Trait for initializing the environments passed to host functions after +/// instantiation but before execution. +/// +/// This is useful for filling an environment with data that can only be accesed +/// after instantiation.

In order to make use of the power of the `wasmer` API, it's important +//! to understand the primitives around which the API is built. +//! +//! Wasm only deals with a small number of core data types, these data +//! types can be found in the [`Value`] type. +//! +//! In addition to the core Wasm types, the core types of the API are +//! referred to as "externs". +//! +//! ## Externs +//! An [`Extern`] is a type that can be imported or exported from a Wasm +//! module. +//! +//! To import an extern, simply give it a namespace and a name with the +//! [`imports`] macro: +//! +//! ``` +//! # use wasmer::{imports, Function, Memory, MemoryType, Store, ImportObject}; +//! # fn imports_example(store: &Store) -> ImportObject { +//! let memory = Memory::new(&store, MemoryType::new(1, None, false)).unwrap(); +//! imports! { +//! "env" => { +//! "my_function" => Function::new_native(store, || println!("Hello")), +//! "memory" => memory, +//! } +//! } +//! # } +//! ``` +//! +//! And to access an exported extern, see the [`Exports`] API, accessible +//! from any instance via `instance.exports`: +//! +//! ``` +//! # use wasmer::{imports, Instance, Function, Memory, NativeFunc}; +//! # fn exports_example(instance: &Instance) -> anyhow::Result<()> { +//! let memory = instance.exports.get_memory("memory")?; +//! let memory: &Memory = instance.exports.get("some_other_memory")?; +//! let add: NativeFunc<(i32, i32), i32> = instance.exports.get_native_function("add")?; +//! let result = add.call(5, 37)?; +//! assert_eq!(result, 42); +//! # Ok(()) +//! # } +//! ``` +//! +//! These are the primary types that the `wasmer` API uses. +//! +//! ### Functions +//! There are 2 types of functions in `wasmer`: +//! 1. Wasm functions +//! 2. Host functions +//! +//! A Wasm function is a function defined in a WebAssembly module that can +//! only perform computation without side effects and call other functions. +//! +//! Wasm functions take 0 or more arguments and return 0 or more results. +//! Wasm functions can only deal with the primitive types defined in +//! [`Value`]. +//! +//! A Host function is any function implemented on the host, in this case in +//! Rust. +//! +//! Host functions can optionally be created with an environment that +//! implements [`WasmerEnv`]. This environment is useful for maintaining +//! host state (for example the filesystem in WASI). +//! +//! Thus WebAssembly modules by themselves cannot do anything but computation +//! on the core types in [`Value`]. In order to make them more useful we +//! give them access to the outside world with [`imports`]. +//! +//! If you're looking for a sandboxed, POSIX-like environment to execute Wasm +//! in, check out the [`wasmer-wasi`][wasmer-wasi] crate for our implementation of WASI, +//! the WebAssembly System Interface. +//! +//! In the `wasmer` API we support functions which take their arguments and +//! return their results dynamically, [`Function`], and functions which +//! take their arguments and return their results statically, [`NativeFunc`]. +//! +//! ### Memories +//! Memories store data. +//! +//! In most Wasm programs, nearly all data will live in a [`Memory`]. +//! +//! This data can be shared between the host and guest to allow for more +//! interesting programs. +//! +//! ### Globals +//! A [`Global`] is a type that may be either mutable or immutable, and +//! contains one of the core Wasm types defined in [`Value`]. +//! +//! ### Tables +//! A [`Table`] is an indexed list of items. +//! +//! +//! ## Project Layout +//! +//! The Wasmer project is divided into a number of crates, below is a dependency +//! graph with transitive dependencies removed. +//! +//!
+//! +//!
+//! +//! While this crate is the top level API, we also publish crates built +//! on top of this API that you may be interested in using, including: +//! +//! - [wasmer-cache][] for caching compiled Wasm modules. +//! - [wasmer-emscripten][] for running Wasm modules compiled to the +//! Emscripten ABI. +//! - [wasmer-wasi][] for running Wasm modules compiled to the WASI ABI. +//! +//! -------- +//! +//! The Wasmer project has two major abstractions: +//! 1. [Engines][wasmer-engine] +//! 2. [Compilers][wasmer-compiler] +//! +//! These two abstractions have multiple options that can be enabled +//! with features. +//! +//! ### Engines +//! +//! An engine is a system that uses a compiler to make a WebAssembly +//! module executable. +//! +//! ### Compilers +//! +//! A compiler is a system that handles the details of making a Wasm +//! module executable. For example, by generating native machine code +//! for each Wasm function. +//! +//! +//! ## Features +//! +//! This crate's features can be broken down into 2 kinds, features that +//! enable new functionality and features that set defaults. +//! +//! The features that enable new functionality are: +//! - `universal` - enable the Universal engine. (See [wasmer-universal][]) +//! - `native` - enable the native engine. (See [wasmer-native][]) +//! - `cranelift` - enable Wasmer's Cranelift compiler. (See [wasmer-cranelift][]) +//! - `llvm` - enable Wasmer's LLVM compiler. (See [wasmer-llvm][]) +//! - `singlepass` - enable Wasmer's Singlepass compiler. (See [wasmer-singlepass][]) +//! - `wat` - enable `wasmer` to parse the WebAssembly text format. +//! +//! The features that set defaults come in sets that are mutually exclusive. +//! +//! The first set is the default compiler set: +//! - `default-cranelift` - set Wasmer's Cranelift compiler as the default. +//! - `default-llvm` - set Wasmer's LLVM compiler as the default. +//! - `default-singlepass` - set Wasmer's Singlepass compiler as the default. +//! +//! The next set is the default engine set: +//! - `default-universal` - set the Universal engine as the default. +//! - `default-native` - set the native engine as the default. +//! +//! -------- +//! +//! By default the `wat`, `default-cranelift`, and `default-universal` features +//! are enabled. +//! +//! +//! +//! [wasm]: https://webassembly.org/ +//!

We got you! -* **Headless mode**: that means that no compilers will be required - to run a `serialized` Module (via `Module::deserialize()`). -* **Cross-compilation**: You can pre-compile a module and serialize it - to then run it in other platform (via `Module::serialize()`). - ## Config flags Wasmer has the following configuration flags: * `wat` (enabled by default): It allows to read WebAssembly files in their text format. *This feature is normally used only in development environments* -* Compilers (mutually exclusive): - - `singlepass`: it will use `wasmer-compiler-singlepass` as the default - compiler (ideal for **blockchains**). - - `cranelift`: it will use `wasmer-compiler-cranelift` as the default - compiler (ideal for **development**). - - `llvm`: it will use `wasmer-compiler-llvm` as the default - compiler (ideal for **production**). - -Wasmer ships by default with the `cranelift` compiler as its great for development proposes. -However, we strongly encourage to use the `llvm` backend in production as it performs -about 50% faster, achieving near-native speeds. - -> Note: if you want to use multiple compilers at the same time, it's also possible! -> You will need to import them directly via each of the compiler crates. --- From ea4682f07948b2a71f9603810e45fea1d9b485b4 Mon Sep 17 00:00:00 2001 From: Syrus Akbary Date: Mon, 21 Jun 2021 21:23:01 -0700 Subject: [PATCH 003/104] Simplified README --- lib/js-api/README.md | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/lib/js-api/README.md b/lib/js-api/README.md index a8a9abe52ab..69df9650e0e 100644 --- a/lib/js-api/README.md +++ b/lib/js-api/README.md @@ -5,9 +5,7 @@ the fastest).

In addition to the core Wasm types, the core types of the API are -//! referred to as "externs". -//! -//! ## Externs -//! An [`Extern`] is a type that can be imported or exported from a Wasm -//! module. -//! -//! To import an extern, simply give it a namespace and a name with the -//! [`imports`] macro: -//! -//! ``` -//! # use wasmer::{imports, Function, Memory, MemoryType, Store, ImportObject}; -//! # fn imports_example(store: &Store) -> ImportObject { -//! let memory = Memory::new(&store, MemoryType::new(1, None, false)).unwrap(); -//! imports! { -//! "env" => { -//! "my_function" => Function::new_native(store, || println!("Hello")), -//! "memory" => memory, -//! } -//! } -//! # } -//! ``` -//! -//! And to access an exported extern, see the [`Exports`] API, accessible -//! from any instance via `instance.exports`: -//! -//! ``` -//! # use wasmer::{imports, Instance, Function, Memory, NativeFunc}; -//! # fn exports_example(instance: &Instance) -> anyhow::Result<()> { -//! let memory = instance.exports.get_memory("memory")?; -//! let memory: &Memory = instance.exports.get("some_other_memory")?; -//! let add: NativeFunc<(i32, i32), i32> = instance.exports.get_native_function("add")?; -//! let result = add.call(5, 37)?; -//! assert_eq!(result, 42); -//! # Ok(()) -//! # } -//! ``` -//! -//! These are the primary types that the `wasmer` API uses. -//! -//! ### Functions -//! There are 2 types of functions in `wasmer`: -//! 1. Wasm functions -//! 2. Host functions -//! -//! A Wasm function is a function defined in a WebAssembly module that can -//! only perform computation without side effects and call other functions. -//! -//! Wasm functions take 0 or more arguments and return 0 or more results. -//! Wasm functions can only deal with the primitive types defined in -//! [`Value`]. -//! -//! A Host function is any function implemented on the host, in this case in -//! Rust. -//! -//! Host functions can optionally be created with an environment that -//! implements [`WasmerEnv`]. This environment is useful for maintaining -//! host state (for example the filesystem in WASI). -//! -//! Thus WebAssembly modules by themselves cannot do anything but computation -//! on the core types in [`Value`]. In order to make them more useful we -//! give them access to the outside world with [`imports`]. -//! -//! If you're looking for a sandboxed, POSIX-like environment to execute Wasm -//! in, check out the [`wasmer-wasi`][wasmer-wasi] crate for our implementation of WASI, -//! the WebAssembly System Interface. -//! -//! In the `wasmer` API we support functions which take their arguments and -//! return their results dynamically, [`Function`], and functions which -//! take their arguments and return their results statically, [`NativeFunc`]. -//! -//! ### Memories -//! Memories store data. -//! -//! In most Wasm programs, nearly all data will live in a [`Memory`]. -//! -//! This data can be shared between the host and guest to allow for more -//! interesting programs. -//! -//! ### Globals -//! A [`Global`] is a type that may be either mutable or immutable, and -//! contains one of the core Wasm types defined in [`Value`]. -//! -//! ### Tables -//! A [`Table`] is an indexed list of items. -//! -//! -//! ## Project Layout -//! -//! The Wasmer project is divided into a number of crates, below is a dependency -//! graph with transitive dependencies removed. -//! -//!
-//! -//!
-//! -//! While this crate is the top level API, we also publish crates built -//! on top of this API that you may be interested in using, including: -//! -//! - [wasmer-cache][] for caching compiled Wasm modules. -//! - [wasmer-emscripten][] for running Wasm modules compiled to the -//! Emscripten ABI. -//! - [wasmer-wasi][] for running Wasm modules compiled to the WASI ABI. -//! -//! -------- -//! -//! The Wasmer project has two major abstractions: -//! 1. [Engines][wasmer-engine] -//! 2. [Compilers][wasmer-compiler] -//! -//! These two abstractions have multiple options that can be enabled -//! with features. -//! -//! ### Engines -//! -//! An engine is a system that uses a compiler to make a WebAssembly -//! module executable. -//! -//! ### Compilers -//! -//! A compiler is a system that handles the details of making a Wasm -//! module executable. For example, by generating native machine code -//! for each Wasm function. -//! -//! -//! ## Features -//! -//! This crate's features can be broken down into 2 kinds, features that -//! enable new functionality and features that set defaults. -//! -//! The features that enable new functionality are: -//! - `universal` - enable the Universal engine. (See [wasmer-universal][]) -//! - `native` - enable the native engine. (See [wasmer-native][]) -//! - `cranelift` - enable Wasmer's Cranelift compiler. (See [wasmer-cranelift][]) -//! - `llvm` - enable Wasmer's LLVM compiler. (See [wasmer-llvm][]) -//! - `singlepass` - enable Wasmer's Singlepass compiler. (See [wasmer-singlepass][]) -//! - `wat` - enable `wasmer` to parse the WebAssembly text format. -//! -//! The features that set defaults come in sets that are mutually exclusive. -//! -//! The first set is the default compiler set: -//! - `default-cranelift` - set Wasmer's Cranelift compiler as the default. -//! - `default-llvm` - set Wasmer's LLVM compiler as the default. -//! - `default-singlepass` - set Wasmer's Singlepass compiler as the default. -//! -//! The next set is the default engine set: -//! - `default-universal` - set the Universal engine as the default. -//! - `default-native` - set the native engine as the default. -//! -//! -------- -//! -//! By default the `wat`, `default-cranelift`, and `default-universal` features -//! are enabled. -//! -//! -//! -//! [wasm]: https://webassembly.org/ -//!

This patch takes the entire `wasmer-js` crate and merges it into the `wasmer` crate. Inside the `lib/api/src/` directory, there are 2 new directories: 1. a new `sys` directory, which contains the usual `wasmer` crate implementation, 2. a new directory `js`, which contains the implementation of `wasmer-js`. The `Cargo.toml` file is still compatible. The `default` feature fallbacks to `sys-default`, which enables the `sys` feature. All features related to compilers or engines or anything else prior this patch, activates the `sys` feature. Parallel to that, there is a `js-default` and `js` features. The `Cargo.toml` file is extensively documented to explain what are dependencies, dev-dependencies, features and other sections related to `sys` or to `js`. There is a bug with `wasm_bindgen_test` where it doesn't compile or look for tests in `tests/*/.rs`. The hack is to name files `tests/js_.rs`. Ugly, but it works. --- Cargo.lock | 24 +- Cargo.toml | 1 - lib/api/Cargo.toml | 241 ++++-- lib/{js-api/src => api/src/js}/cell.rs | 0 lib/{js-api/src => api/src/js}/env.rs | 2 +- lib/{js-api/src => api/src/js}/error.rs | 2 +- lib/{js-api/src => api/src/js}/export.rs | 8 +- lib/{js-api/src => api/src/js}/exports.rs | 18 +- .../src => api/src/js}/externals/function.rs | 18 +- .../src => api/src/js}/externals/global.rs | 20 +- .../src => api/src/js}/externals/memory.rs | 12 +- .../src => api/src/js}/externals/mod.rs | 8 +- .../src => api/src/js}/externals/table.rs | 18 +- .../src => api/src/js}/import_object.rs | 12 +- lib/{js-api/src => api/src/js}/instance.rs | 18 +- lib/{js-api/src/lib.rs => api/src/js/mod.rs} | 30 +- lib/{js-api/src => api/src/js}/module.rs | 18 +- .../src/js}/module_info_polyfill.rs | 0 lib/{js-api/src => api/src/js}/native.rs | 14 +- lib/{js-api/src => api/src/js}/ptr.rs | 6 +- lib/{js-api/src => api/src/js}/resolver.rs | 2 +- lib/{js-api/src => api/src/js}/store.rs | 0 lib/{js-api/src => api/src/js}/trap.rs | 0 lib/{js-api/src => api/src/js}/types.rs | 6 +- lib/api/src/{ => js}/utils.rs | 0 .../src/js}/wasm_bindgen_polyfill.rs | 0 lib/api/src/lib.rs | 392 +--------- lib/api/src/{ => sys}/cell.rs | 0 lib/api/src/{ => sys}/env.rs | 2 +- lib/api/src/{ => sys}/exports.rs | 8 +- lib/api/src/{ => sys}/externals/function.rs | 16 +- lib/api/src/{ => sys}/externals/global.rs | 14 +- lib/api/src/{ => sys}/externals/memory.rs | 8 +- lib/api/src/{ => sys}/externals/mod.rs | 6 +- lib/api/src/{ => sys}/externals/table.rs | 12 +- lib/api/src/{ => sys}/import_object.rs | 4 +- lib/api/src/{ => sys}/instance.rs | 10 +- lib/api/src/sys/mod.rs | 384 +++++++++ lib/api/src/{ => sys}/module.rs | 6 +- lib/api/src/{ => sys}/native.rs | 12 +- lib/api/src/{ => sys}/ptr.rs | 6 +- lib/api/src/{ => sys}/store.rs | 2 +- lib/api/src/{ => sys}/tunables.rs | 2 +- lib/api/src/{ => sys}/types.rs | 6 +- lib/{js-api/src => api/src/sys}/utils.rs | 0 lib/api/tests/export.rs | 334 -------- lib/api/tests/externals.rs | 458 ----------- lib/api/tests/instance.rs | 39 -

In order to make use of the power of the `wasmer` API, it's important -//! to understand the primitives around which the API is built. -//! -//! Wasm only deals with a small number of core data types, these data -//! types can be found in the [`Value`] type. -//! -//! In addition to the core Wasm types, the core types of the API are -//! referred to as "externs". -//! -//! ## Externs -//! An [`Extern`] is a type that can be imported or exported from a Wasm -//! module. -//! -//! To import an extern, simply give it a namespace and a name with the -//! [`imports`] macro: -//! -//! ``` -//! # use wasmer::{imports, Function, Memory, MemoryType, Store, ImportObject}; -//! # fn imports_example(store: &Store) -> ImportObject { -//! let memory = Memory::new(&store, MemoryType::new(1, None, false)).unwrap(); -//! imports! { -//! "env" => { -//! "my_function" => Function::new_native(store, || println!("Hello")), -//! "memory" => memory, -//! } -//! } -//! # } -//! ``` -//! -//! And to access an exported extern, see the [`Exports`] API, accessible -//! from any instance via `instance.exports`: -//! -//! ``` -//! # use wasmer::{imports, Instance, Function, Memory, NativeFunc}; -//! # fn exports_example(instance: &Instance) -> anyhow::Result<()> { -//! let memory = instance.exports.get_memory("memory")?; -//! let memory: &Memory = instance.exports.get("some_other_memory")?; -//! let add: NativeFunc<(i32, i32), i32> = instance.exports.get_native_function("add")?; -//! let result = add.call(5, 37)?; -//! assert_eq!(result, 42); -//! # Ok(()) -//! # } -//! ``` -//! -//! These are the primary types that the `wasmer` API uses. -//! -//! ### Functions -//! There are 2 types of functions in `wasmer`: -//! 1. Wasm functions -//! 2. Host functions -//! -//! A Wasm function is a function defined in a WebAssembly module that can -//! only perform computation without side effects and call other functions. -//! -//! Wasm functions take 0 or more arguments and return 0 or more results. -//! Wasm functions can only deal with the primitive types defined in -//! [`Value`]. -//! -//! A Host function is any function implemented on the host, in this case in -//! Rust. -//! -//! Host functions can optionally be created with an environment that -//! implements [`WasmerEnv`]. This environment is useful for maintaining -//! host state (for example the filesystem in WASI). -//! -//! Thus WebAssembly modules by themselves cannot do anything but computation -//! on the core types in [`Value`]. In order to make them more useful we -//! give them access to the outside world with [`imports`]. -//! -//! If you're looking for a sandboxed, POSIX-like environment to execute Wasm -//! in, check out the [`wasmer-wasi`][wasmer-wasi] crate for our implementation of WASI, -//! the WebAssembly System Interface. -//! -//! In the `wasmer` API we support functions which take their arguments and -//! return their results dynamically, [`Function`], and functions which -//! take their arguments and return their results statically, [`NativeFunc`]. -//! -//! ### Memories -//! Memories store data. -//! -//! In most Wasm programs, nearly all data will live in a [`Memory`]. -//! -//! This data can be shared between the host and guest to allow for more -//! interesting programs. -//! -//! ### Globals -//! A [`Global`] is a type that may be either mutable or immutable, and -//! contains one of the core Wasm types defined in [`Value`]. -//! -//! ### Tables -//! A [`Table`] is an indexed list of items. -//! -//! -//! ## Project Layout -//! -//! The Wasmer project is divided into a number of crates, below is a dependency -//! graph with transitive dependencies removed. -//! -//!
-//! -//!
-//! -//! While this crate is the top level API, we also publish crates built -//! on top of this API that you may be interested in using, including: -//! -//! - [wasmer-cache][] for caching compiled Wasm modules. -//! - [wasmer-emscripten][] for running Wasm modules compiled to the -//! Emscripten ABI. -//! - [wasmer-wasi][] for running Wasm modules compiled to the WASI ABI. -//! -//! -------- -//! -//! The Wasmer project has two major abstractions: -//! 1. [Engines][wasmer-engine] -//! 2. [Compilers][wasmer-compiler] -//! -//! These two abstractions have multiple options that can be enabled -//! with features. -//! -//! ### Engines -//! -//! An engine is a system that uses a compiler to make a WebAssembly -//! module executable. -//! -//! ### Compilers -//! -//! A compiler is a system that handles the details of making a Wasm -//! module executable. For example, by generating native machine code -//! for each Wasm function. -//! -//! -//! ## Features -//! -//! This crate's features can be broken down into 2 kinds, features that -//! enable new functionality and features that set defaults. -//! -//! The features that enable new functionality are: -//! - `universal` - enable the Universal engine. (See [wasmer-universal][]) -//! - `native` - enable the native engine. (See [wasmer-native][]) -//! - `cranelift` - enable Wasmer's Cranelift compiler. (See [wasmer-cranelift][]) -//! - `llvm` - enable Wasmer's LLVM compiler. (See [wasmer-llvm][]) -//! - `singlepass` - enable Wasmer's Singlepass compiler. (See [wasmer-singlepass][]) -//! - `wat` - enable `wasmer` to parse the WebAssembly text format. -//! -//! The features that set defaults come in sets that are mutually exclusive. -//! -//! The first set is the default compiler set: -//! - `default-cranelift` - set Wasmer's Cranelift compiler as the default. -//! - `default-llvm` - set Wasmer's LLVM compiler as the default. -//! - `default-singlepass` - set Wasmer's Singlepass compiler as the default. -//! -//! The next set is the default engine set: -//! - `default-universal` - set the Universal engine as the default. -//! - `default-native` - set the native engine as the default. -//! -//! -------- -//! -//! By default the `wat`, `default-cranelift`, and `default-universal` features -//! are enabled. -//! -//! -//! -//! [wasm]: https://webassembly.org/ -//!

(module +//! (type $t0 (func (param i32) (result i32))) +//! (func $add_one (export "add_one") (type $t0) (param $p0 i32) (result i32) +//! get_local $p0 +//! i32.const 1 +//! i32.add)) +//! "#; +//! +//! let store = Store::default(); +//! let module = Module::new(&store, &module_wat)?; +//! // The module doesn't import anything, so we create an empty import object. +//! let import_object = imports! {}; +//! let instance = Instance::new(&module, &import_object)?; +//! +//! let add_one = instance.exports.get_function("add_one")?; +//! let result = add_one.call(&[Value::I32(42)])?; +//! assert_eq!(result[0], Value::I32(43)); +//! +//! Ok(()) +//! } +//! ``` +//! +//! For more examples of using the `wasmer` API, check out the +//! [wasmer examples][wasmer-examples]. +//! +//! --------- +//! +//! # Table of Contents +//! +//! - [Wasm Primitives](#wasm-primitives) +//! - [Externs](#externs) +//! - [Functions](#functions) +//! - [Memories](#memories) +//! - [Globals](#globals) +//! - [Tables](#tables) +//! - [Project Layout](#project-layout) +//! - [Engines](#engines) +//! - [Compilers](#compilers) +//! - [Features](#features) +//! +//! +//! # Wasm Primitives +//! In order to make use of the power of the `wasmer` API, it's important +//! to understand the primitives around which the API is built. +//! +//! Wasm only deals with a small number of core data types, these data +//! types can be found in the [`Value`] type. +//! +//! In addition to the core Wasm types, the core types of the API are +//! referred to as "externs". +//! +//! ## Externs +//! An [`Extern`] is a type that can be imported or exported from a Wasm +//! module. +//! +//! To import an extern, simply give it a namespace and a name with the +//! [`imports`] macro: +//! +//! ``` +//! # use wasmer::{imports, Function, Memory, MemoryType, Store, ImportObject}; +//! # fn imports_example(store: &Store) -> ImportObject { +//! let memory = Memory::new(&store, MemoryType::new(1, None, false)).unwrap(); +//! imports! { +//! "env" => { +//! "my_function" => Function::new_native(store, || println!("Hello")), +//! "memory" => memory, +//! } +//! } +//! # } +//! ``` +//! +//! And to access an exported extern, see the [`Exports`] API, accessible +//! from any instance via `instance.exports`: +//! +//! ``` +//! # use wasmer::{imports, Instance, Function, Memory, NativeFunc}; +//! # fn exports_example(instance: &Instance) -> anyhow::Result<()> { +//! let memory = instance.exports.get_memory("memory")?; +//! let memory: &Memory = instance.exports.get("some_other_memory")?; +//! let add: NativeFunc<(i32, i32), i32> = instance.exports.get_native_function("add")?; +//! let result = add.call(5, 37)?; +//! assert_eq!(result, 42); +//! # Ok(()) +//! # } +//! ``` +//! +//! These are the primary types that the `wasmer` API uses. +//! +//! ### Functions +//! There are 2 types of functions in `wasmer`: +//! 1. Wasm functions +//! 2. Host functions +//! +//! A Wasm function is a function defined in a WebAssembly module that can +//! only perform computation without side effects and call other functions. +//! +//! Wasm functions take 0 or more arguments and return 0 or more results. +//! Wasm functions can only deal with the primitive types defined in +//! [`Value`]. +//! +//! A Host function is any function implemented on the host, in this case in +//! Rust. +//! +//! Host functions can optionally be created with an environment that +//! implements [`WasmerEnv`]. This environment is useful for maintaining +//! host state (for example the filesystem in WASI). +//! +//! Thus WebAssembly modules by themselves cannot do anything but computation +//! on the core types in [`Value`]. In order to make them more useful we +//! give them access to the outside world with [`imports`]. +//! +//! If you're looking for a sandboxed, POSIX-like environment to execute Wasm +//! in, check out the [`wasmer-wasi`][wasmer-wasi] crate for our implementation of WASI, +//! the WebAssembly System Interface. +//! +//! In the `wasmer` API we support functions which take their arguments and +//! return their results dynamically, [`Function`], and functions which +//! take their arguments and return their results statically, [`NativeFunc`]. +//! +//! ### Memories +//! Memories store data. +//! +//! In most Wasm programs, nearly all data will live in a [`Memory`]. +//! +//! This data can be shared between the host and guest to allow for more +//! interesting programs. +//! +//! ### Globals +//! A [`Global`] is a type that may be either mutable or immutable, and +//! contains one of the core Wasm types defined in [`Value`]. +//! +//! ### Tables +//! A [`Table`] is an indexed list of items. +//! +//! +//! ## Project Layout +//! +//! The Wasmer project is divided into a number of crates, below is a dependency +//! graph with transitive dependencies removed. +//! +//!
+//! +//!
+//! +//! While this crate is the top level API, we also publish crates built +//! on top of this API that you may be interested in using, including: +//! +//! - [wasmer-cache][] for caching compiled Wasm modules. +//! - [wasmer-emscripten][] for running Wasm modules compiled to the +//! Emscripten ABI. +//! - [wasmer-wasi][] for running Wasm modules compiled to the WASI ABI. +//! +//! -------- +//! +//! The Wasmer project has two major abstractions: +//! 1. [Engines][wasmer-engine] +//! 2. [Compilers][wasmer-compiler] +//! +//! These two abstractions have multiple options that can be enabled +//! with features. +//! +//! ### Engines +//! +//! An engine is a system that uses a compiler to make a WebAssembly +//! module executable. +//! +//! ### Compilers +//! +//! A compiler is a system that handles the details of making a Wasm +//! module executable. For example, by generating native machine code +//! for each Wasm function. +//! +//! +//! ## Features +//! +//! This crate's features can be broken down into 2 kinds, features that +//! enable new functionality and features that set defaults. +//! +//! The features that enable new functionality are: +//! - `universal` - enable the Universal engine. (See [wasmer-universal][]) +//! - `native` - enable the native engine. (See [wasmer-native][]) +//! - `cranelift` - enable Wasmer's Cranelift compiler. (See [wasmer-cranelift][]) +//! - `llvm` - enable Wasmer's LLVM compiler. (See [wasmer-llvm][]) +//! - `singlepass` - enable Wasmer's Singlepass compiler. (See [wasmer-singlepass][]) +//! - `wat` - enable `wasmer` to parse the WebAssembly text format. +//! +//! The features that set defaults come in sets that are mutually exclusive. +//! +//! The first set is the default compiler set: +//! - `default-cranelift` - set Wasmer's Cranelift compiler as the default. +//! - `default-llvm` - set Wasmer's LLVM compiler as the default. +//! - `default-singlepass` - set Wasmer's Singlepass compiler as the default. +//! +//! The next set is the default engine set: +//! - `default-universal` - set the Universal engine as the default. +//! - `default-native` - set the native engine as the default. +//! +//! -------- +//! +//! By default the `wat`, `default-cranelift`, and `default-universal` features +//! are enabled. +//! +//! +//! +//! [wasm]: https://webassembly.org/ +//!

In addition to the core Wasm types, the core types of the API are +//! referred to as "externs". +//! +//! ## Externs +//! An [`Extern`] is a type that can be imported or exported from a Wasm +//! module. +//! +//! To import an extern, simply give it a namespace and a name with the +//! [`imports`] macro: +//! +//! ``` +//! # use wasmer::{imports, Function, Memory, MemoryType, Store, ImportObject}; +//! # fn imports_example(store: &Store) -> ImportObject { +//! let memory = Memory::new(&store, MemoryType::new(1, None, false)).unwrap(); +//! imports! { +//!

These are the primary types that the `wasmer` API uses. +//! +//! ### Functions +//! There are 2 types of functions in `wasmer`: +//! 1. Wasm functions, +//! 2. Host functions. +//! +//! A Wasm function is a function defined in a WebAssembly module that can +//! only perform computation without side effects and call other functions. +//! +//! Wasm functions take 0 or more arguments and return 0 or more results. +//! Wasm functions can only deal with the primitive types defined in +//! [`Value`]. +//! +//! A Host function is any function implemented on the host, in this case in +//! Rust. +//! +//! Host functions can optionally be created with an environment that +//! implements [`WasmerEnv`]. This environment is useful for maintaining +//! host state (for example the filesystem in WASI). +//! +//! Thus WebAssembly modules by themselves cannot do anything but computation +//! on the core types in [`Value`]. In order to make them more useful we +//! give them access to the outside world with [`imports`]. +//! +//! If you're looking for a sandboxed, POSIX-like environment to execute Wasm +//! in, check out the [`wasmer-wasi`][wasmer-wasi] crate for our implementation of WASI, +//! the WebAssembly System Interface. +//! +//! In the `wasmer` API we support functions which take their arguments and +//! return their results dynamically, [`Function`], and functions which +//! take their arguments and return their results statically, [`NativeFunc`]. +//! +//! ### Memories +//! Memories store data. +//! +//! In most Wasm programs, nearly all data will live in a [`Memory`]. +//! +//! This data can be shared between the host and guest to allow for more +//! interesting programs. +//! +//! ### Globals +//! A [`Global`] is a type that may be either mutable or immutable, and +//! contains one of the core Wasm types defined in [`Value`]. +//! +//! ### Tables +//! A [`Table`] is an indexed list of items. +//! +//! +//! ## Project Layout +//! +//! The Wasmer project is divided into a number of crates, below is a dependency +//! graph with transitive dependencies removed. +//! +//!
+//! +//!
+//! +//! While this crate is the top level API, we also publish crates built +//! on top of this API that you may be interested in using, including: +//! +//! - [wasmer-cache] for caching compiled Wasm modules, +//! - [wasmer-emscripten] for running Wasm modules compiled to the +//! Emscripten ABI, +//! - [wasmer-wasi] for running Wasm modules compiled to the WASI ABI. +//! +//! The Wasmer project has two major abstractions: +//! 1. [Engines][wasmer-engine], +//! 2. [Compilers][wasmer-compiler]. +//! +//! These two abstractions have multiple options that can be enabled +//! with features. +//! +//! ### Engines +//! +//! An engine is a system that uses a compiler to make a WebAssembly +//! module executable. +//! +//! ### Compilers +//! +//! A compiler is a system that handles the details of making a Wasm +//! module executable. For example, by generating native machine code +//! for each Wasm function. +//! +//! +//! ## Features +//! +//! This crate comes in 2 flavors: +//! +//! 1. `sys` +#![cfg_attr(feature = "sys", doc = "(enabled),")] +#![cfg_attr(not(feature = "sys"), doc = "(disabled),")] +//! where `wasmer` will be compiled to a native executable +//! which provides compilers, engines, a full VM etc. +//! 2. `js` +#![cfg_attr(feature = "js", doc = "(enabled),")] +#![cfg_attr(not(feature = "js"), doc = "(disabled),")] +//! where `wasmer` will be compiled to WebAssembly to run in a +//! JavaScript host. +//! +//! Consequently, we can group the features by the `sys` or `js` +//! features. +//! +#![cfg_attr( + feature = "sys", + doc = "### Features for the `sys` feature group (enabled)" +)] +#![cfg_attr( + not(feature = "sys"), + doc = "### Features for the `sys` feature group (disabled)" +)] +//! +//! The default features can be enabled with the `sys-default` feature. +//! +//! The features for the `sys` feature group can be broken down into 2 +//! kinds: features that enable new functionality and features that +//! set defaults. +//! +//! The features that enable new functionality are: +//! - `cranelift` +#![cfg_attr(feature = "cranelift", doc = "(enabled),")] +#![cfg_attr(not(feature = "cranelift"), doc = "(disabled),")] +//! enables Wasmer's [Cranelift compiler][wasmer-cranelift], +//! - `llvm` +#![cfg_attr(feature = "llvm", doc = "(enabled),")] +#![cfg_attr(not(feature = "llvm"), doc = "(disabled),")] +//! enables Wasmer's [LLVM compiler][wasmer-llvm], +//! - `singlepass` +#![cfg_attr(feature = "singlepass", doc = "(enabled),")] +#![cfg_attr(not(feature = "singlepass"), doc = "(disabled),")] +//! enables Wasmer's [Singlepass compiler][wasmer-singlepass], +//! - `wat` +#![cfg_attr(feature = "wat", doc = "(enabled),")] +#![cfg_attr(not(feature = "wat"), doc = "(disabled),")] +//! enables `wasmer` to parse the WebAssembly text format, +//! - `universal` +#![cfg_attr(feature = "universal", doc = "(enabled),")] +#![cfg_attr(not(feature = "universal"), doc = "(disabled),")] +//! enables [the Universal engine][wasmer-universal], +//! - `dylib` +#![cfg_attr(feature = "dylib", doc = "(enabled),")] +#![cfg_attr(not(feature = "dylib"), doc = "(disabled),")] +//! enables [the Dylib engine][wasmer-dylib]. +//! +//! The features that set defaults come in sets that are mutually exclusive. +//! +//! The first set is the default compiler set: +//! - `default-cranelift` +#![cfg_attr(feature = "default-cranelift", doc = "(enabled),")] +#![cfg_attr(not(feature = "default-cranelift"), doc = "(disabled),")] +//! set Wasmer's Cranelift compiler as the default, +//! - `default-llvm` +#![cfg_attr(feature = "default-llvm", doc = "(enabled),")] +#![cfg_attr(not(feature = "default-llvm"), doc = "(disabled),")] +//! set Wasmer's LLVM compiler as the default, +//! - `default-singlepass` +#![cfg_attr(feature = "default-singlepass", doc = "(enabled),")] +#![cfg_attr(not(feature = "default-singlepass"), doc = "(disabled),")] +//! set Wasmer's Singlepass compiler as the default. +//! +//! The next set is the default engine set: +//! - `default-universal` +#![cfg_attr(feature = "default-universal", doc = "(enabled),")] +#![cfg_attr(not(feature = "default-universal"), doc = "(disabled),")] +//! set the Universal engine as the default, +//! - `default-dylib` +#![cfg_attr(feature = "default-dylib", doc = "(enabled),")] +#![cfg_attr(not(feature = "default-dylib"), doc = "(disabled),")] +//! set the Dylib engine as the default. +//! +#![cfg_attr( + feature = "js", + doc = "### Features for the `js` feature group (enabled)" +)] +#![cfg_attr( + not(feature = "js"), + doc = "### Features for the `js` feature group (disabled)" +)] +//! +//! The default features can be enabled with the `js-default` feature. +//! +//! Here are the detailed list of features: +//! +//! - `wasm-types-polyfill` +#![cfg_attr(feature = "wasm-types-polyfill", doc = "(enabled),")] +#![cfg_attr(not(feature = "wasm-types-polyfill"), doc = "(disabled),")] +//! parses the Wasm file, allowing to do type reflection of the +//! inner Wasm types. It adds 100kb to the Wasm bundle (28kb +//! gzipped). It is possible to disable it and to use +//! `Module::set_type_hints` manually instead for a lightweight +//! alternative. This is needed until the [Wasm JS introspection API +//! proposal](https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md) +//! is adopted by browsers, +//! - `wat` +#![cfg_attr(feature = "wat", doc = "(enabled),")] +#![cfg_attr(not(feature = "wat"), doc = "(disabled),")] +//! allows to read a Wasm file in its text format. This feature is +//! normally used only in development environments. It will add +//! around 650kb to the Wasm bundle (120Kb gzipped). +//! +//! +//! [wasm]: https://webassembly.org/ +//!

And to access an exported extern, see the [`Exports`] API, accessible -//! from any instance via `instance.exports`: -//! -//! ``` -//! # use wasmer::{imports, Instance, Function, Memory, NativeFunc}; -//! # fn exports_example(instance: &Instance) -> anyhow::Result<()> { -//! let memory = instance.exports.get_memory("memory")?; -//! let memory: &Memory = instance.exports.get("some_other_memory")?; -//! let add: NativeFunc<(i32, i32), i32> = instance.exports.get_native_function("add")?; -//! let result = add.call(5, 37)?; -//! assert_eq!(result, 42); -//! # Ok(()) -//! # } -//! ``` -//! -//! These are the primary types that the `wasmer` API uses. -//! -//! ### Functions -//! There are 2 types of functions in `wasmer`: -//! 1. Wasm functions -//! 2. Host functions -//! -//! A Wasm function is a function defined in a WebAssembly module that can -//! only perform computation without side effects and call other functions. -//! -//! Wasm functions take 0 or more arguments and return 0 or more results. -//! Wasm functions can only deal with the primitive types defined in -//! [`Value`]. -//! -//! A Host function is any function implemented on the host, in this case in -//! Rust. -//! -//! Host functions can optionally be created with an environment that -//! implements [`WasmerEnv`]. This environment is useful for maintaining -//! host state (for example the filesystem in WASI). -//! -//! Thus WebAssembly modules by themselves cannot do anything but computation -//! on the core types in [`Value`]. In order to make them more useful we -//! give them access to the outside world with [`imports`]. -//! -//! If you're looking for a sandboxed, POSIX-like environment to execute Wasm -//! in, check out the [`wasmer-wasi`][wasmer-wasi] crate for our implementation of WASI, -//! the WebAssembly System Interface. -//! -//! In the `wasmer` API we support functions which take their arguments and -//! return their results dynamically, [`Function`], and functions which -//! take their arguments and return their results statically, [`NativeFunc`]. -//! -//! ### Memories -//! Memories store data. -//! -//! In most Wasm programs, nearly all data will live in a [`Memory`]. -//! -//! This data can be shared between the host and guest to allow for more -//! interesting programs. -//! -//! ### Globals -//! A [`Global`] is a type that may be either mutable or immutable, and -//! contains one of the core Wasm types defined in [`Value`]. -//! -//! ### Tables -//! A [`Table`] is an indexed list of items. -//! -//! -//! ## Project Layout -//! -//! The Wasmer project is divided into a number of crates, below is a dependency -//! graph with transitive dependencies removed. -//! -//!
-//! -//!
-//! -//! While this crate is the top level API, we also publish crates built -//! on top of this API that you may be interested in using, including: -//! -//! - [wasmer-cache][] for caching compiled Wasm modules. -//! - [wasmer-emscripten][] for running Wasm modules compiled to the -//! Emscripten ABI. -//! - [wasmer-wasi][] for running Wasm modules compiled to the WASI ABI. -//! -//! -------- -//! -//! The Wasmer project has two major abstractions: -//! 1. [Engines][wasmer-engine] -//! 2. [Compilers][wasmer-compiler] -//! -//! These two abstractions have multiple options that can be enabled -//! with features. -//! -//! ### Engines -//! -//! An engine is a system that uses a compiler to make a WebAssembly -//! module executable. -//! -//! ### Compilers -//! -//! A compiler is a system that handles the details of making a Wasm -//! module executable. For example, by generating native machine code -//! for each Wasm function. -//! -//! -//! ## Features -//! -//! This crate's features can be broken down into 2 kinds, features that -//! enable new functionality and features that set defaults. -//! -//! The features that enable new functionality are: -//! - `universal` - enable the Universal engine. (See [wasmer-universal][]) -//! - `native` - enable the native engine. (See [wasmer-native][]) -//! - `cranelift` - enable Wasmer's Cranelift compiler. (See [wasmer-cranelift][]) -//! - `llvm` - enable Wasmer's LLVM compiler. (See [wasmer-llvm][]) -//! - `singlepass` - enable Wasmer's Singlepass compiler. (See [wasmer-singlepass][]) -//! - `wat` - enable `wasmer` to parse the WebAssembly text format. -//! -//! The features that set defaults come in sets that are mutually exclusive. -//! -//! The first set is the default compiler set: -//! - `default-cranelift` - set Wasmer's Cranelift compiler as the default. -//! - `default-llvm` - set Wasmer's LLVM compiler as the default. -//! - `default-singlepass` - set Wasmer's Singlepass compiler as the default. -//! -//! The next set is the default engine set: -//! - `default-universal` - set the Universal engine as the default. -//! - `default-native` - set the native engine as the default. -//! -//! -------- -//! -//! By default the `wat`, `default-cranelift`, and `default-universal` features -//! are enabled. -//! -//! -//! -//! [wasm]: https://webassembly.org/ -//!
