This crate is the base for Compiler implementations.

It performs the translation from a Wasm module into a basic ModuleInfo, but leaves the Wasm function bytecode translation to the compiler implementor.

Here are some of the Compilers provided by Wasmer:

How to create a compiler

To create a compiler, one needs to implement two traits:

  1. CompilerConfig, that configures and creates a new compiler,
  2. Compiler, the compiler itself that will compile a module.
/// The compiler configuration options.
pub trait CompilerConfig {
    /// Gets the custom compiler config
    fn compiler(&self) -> Box<dyn Compiler>;
}

/// An implementation of a compiler from parsed WebAssembly module to compiled native code.
pub trait Compiler {
    /// Compiles a parsed module.
    ///
    /// It returns the [`Compilation`] or a [`CompileError`].
    fn compile_module<'data, 'module>(
        &self,
        target: &Target,
        compile_info: &'module CompileModuleInfo,
        module_translation: &ModuleTranslationState,
        // The list of function bodies
        function_body_inputs: PrimaryMap<LocalFunctionIndex, FunctionBodyData<'data>>,
    ) -> Result<Compilation, CompileError>;
}

Acknowledgments

This project borrowed some of the code strucutre from the cranelift-wasm crate, however it's been adapted to not depend on any specific IR and be abstract of any compiler.
