High-level API to expose the Wasmtime runtime

//! Architecture-specific support required by Wasmtime.
//!
//! This crate houses any architecture-specific tidbits required when running
//! Wasmtime. Each architecture has its own file in the `arch` folder which is
//! referenced here.
//!
//! All architectures have the same interface when exposed to the rest of the
//! crate.
