All cases of our transmute can be replaced with more idiomatic solutions and do no require the power of transmute. When returning an object to C for life-time management, use Box::into_raw to convert the boxed object to pointer and use Box::from_raw to convert back. For cases where we're just returning a pointer to Rust managed data, use a cast.
Based on the Rust clippy lint that recommends that any public function that dereferences a raw pointer, mark all FFI functions that reference raw pointers with build_slice and cast_pointer as unsafe. This commits starts by removing the unsafe wrapper inside the build_slice and cast_pointer macros then marks all functions that use these macros as unsafe. Then fix all not_unsafe_ptr_arg_deref warnings from clippy. Fixes clippy lint: https://rust-lang.github.io/rust-clippy/master/index.html#not_unsafe_ptr_arg_deref
These are needless borrows (references) as the item is already a reference.
This lint checks for a closure where a function can be directly supplied. Runtime performance is unchanged, but this makes less work for the compiler.
Calling a function in unwrap_or causes that function to always be called even when not needed. Instead use unwrap_or_else with a closure which will only be called when needed.
In these simple cases to_string() is recommended and likely performs better as the formatter is not called.
These add complexity and may not be optimized out by the compiler.
This is a readability fix, as on first look they almost look like a Rust tuple.
This is code that is not needed and is a bit confusing to see.
When defaulting checked_mul to u64::max, Rust has a method that does the same thing called saturating_mul.
- ref is discouraged for top level variables - the other borrow is not required
This is the preffered style and easier to understand the meaning of the code.
Using `if let` expressions in these cases is better expressed by the map method, and considered idiomatic Rust for this usage.
Suppress all remaining clippy lints that we trip. This can be fixed on a per-lint basis.
