# Waxosuit Codec
Underneath [waxosuit](https://waxosuit.io) lies the [waPC](https://github.com/wapc) (WebAssembly Procedure Calls) mechanism for communicating across the host/guest boundary.
Above that layer Waxosuit has created a number of protobuf and Rust-native types and helper methods which are included in this crate. Only use this crate if you're working within the Waxosuit ecosystem.
This crate includes the well-known messages and operations that Waxosuit must support out of the box, such as **messaging**, **key-value store**, and **HTTP client/server**.
