//! # Wasmtime's WASI Implementation
//!
//! This crate provides a Wasmtime host implementations of different versions of WASI.
//! WASI is implemented with the Rust crates [`tokio`] and [`cap-std`](cap_std) primarily, meaning that
//! operations are implemented in terms of their native platform equivalents by
//! default.
//!
//! For components and WASIp2, see [`p2`].
//! For WASIp1 and core modules, see the [`preview1`] module documentation.
//!
//! For WASIp3, see [`p3`]. WASIp3 support is experimental, unstable and incomplete.
