//! Internal dependency of the `wasmtime` crate.
//!
//! This crate is responsible for defining types and basic runtime structures
//! used by the `wasmtime` crate. This additionally defines primitives of
//! compilation and what compilers are expected to emit.
//!
//! If you don't already know what this crate is you probably want to use
//! `wasmtime`, not this crate.
