Trait WasmRuntime

pub trait WasmRuntime<T>: Clone
where
    T: ProcessState + Default + Send,
{
    type WasmInstance: WasmInstance;

    // Required methods
    fn compile_module(&mut self, data: RawWasm) -> Result<usize>;
    fn wasm_module(&self, index: usize) -> Option<&RawWasm>;
}

A WasmRuntime is a compiler that can generate runnable code from raw .wasm files.

It also provides a mechanism to register host functions that are accessible to the wasm guest code through the generic type T. The type T must implement the ProcessState trait and expose a register function for host functions.

Required Associated Types

type WasmInstance: WasmInstance

Required Methods

fn compile_module(&mut self, data: RawWasm) -> Result<usize>

Takes a raw binary WebAssembly module and returns the index of a compiled module.

fn wasm_module(&self, index: usize) -> Option<&RawWasm>

Returns a reference to the raw binary WebAssembly module if the index exists.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
