Rust bindings for Binaryen's wasm-opt

wasm-opt is a component of the Binaryen toolkit that optimizes WebAssembly modules. It is written in C++.

lib.rs:

Native build of wasm-opt.

This crate builds the C++ code for wasm-opt but does not provide any Rust bindings.

Rust bindings can be found in wasm-opt-cxx-sys, but most users will probably want the high level APIs in the wasm-opt crate.
