wasm3-rs

Rust wrapper for WASM3.

This is currently very much work in progress and may or may not be sound.

Sample

A simple example that loads a wasm module and executes an exported function to add two i64s together.

use wasm3::environment::Environment;
use wasm3::module::Module;

fn main() {
    let env = Environment::new();
    let rt = env.create_runtime(1024 * 60);
    let data = include_bytes!("wasm/wasm-add/wasm_add.wasm");
    let module = Module::parse(&env, &data[..]).unwrap();

    assert!(rt.load_module(module).is_ok());
    let func = rt.find_function::<(i64, i64), i64>("add").unwrap();
    println!("Wasm says that 3 + 6 is {}", func.call(3, 6).unwrap())
}

Building

This crate currently does not make use of the cmake project of wasm3, meaning cmake is not required to built this for the time being. It does however require Clang 9 to be installed.
