Export wasmer::sys::module::IoCompileError

[jvff]

Motivation

There's an error type returned from Module::from_file that is public but isn't exported from the crate. It's therefore impossible to import that type to match against the error in a project that uses the wasmer crate.

It's also impossible to do something like

#[derive(Debug, thiserror::Error)]
pub enum CustomError {
    #[error("Failed to load Wasm module")]
    InvalidModule(#[from] wasmer::IoCompileError), // How to import `IoCompileError`?

    // ...
}

Solutions

The simplest solution might be to just export the error type from the root module of the wasmer crate.

An alternative is to change the error type returned by Module::from_file, if the IoCompileError shouldn't be public.
