binaryen-rs

Binaryen bindings for Rust.

With Binaryen you can create optimized WebAssembly modules.

For example what you can create with Binaryen you can check out DEMO*. Yes, this is CHIP-8 roms compiled straight to the WebAssembly. See emchipten test bed for this project.

Example

```rust extern crate binaryen;

use binaryen::*;

fn main() { let module = Module::new();

let params = &[ValueTy::I32, ValueTy::I32];
let iii = module.add_fn_type(Some("iii"), params, Ty::I32);

let x = module.get_local(0, ValueTy::I32);
let y = module.get_local(1, ValueTy::I32);
let add = module.binary(BinaryOp::AddI32, x, y);

let _adder = module.add_fn("adder", &iii, &[], add);

assert!(module.is_valid());

module.print();

} ```

This example will print:

WebAssembly (module (type $iii (func (param i32 i32) (result i32))) (memory $0 0) (func $adder (type $iii) (param $0 i32) (param $1 i32) (result i32) (i32.add (get_local $0) (get_local $1) ) ) )
