wasm-opt-cxx-sys 0.116.0

//! Direct bindings to `wasm-opt`.
//!
//! These are bindings to `wasm-opt`,
//! as built by the [`wasm-opt-sys`] crate.
//! The bindings are created by the [`cxx`] crate,
//! and all go through a custom C++ shim layer
//! that provides a `cxx`-compatible C++ API.
//!
//! Most users will not want to use this crate directly,
//! but instead the [`wasm-opt`] crate.
//!
//! [`wasm-opt-sys`]: https://docs.rs/wasm-opt-sys
//! [`cxx`]: https://docs.rs/cxx
//! [`wasm-opt`]: https://docs.rs/wasm-opt
//!
//! The version of `cxx` used by these bindings is
//! reexported here.
