8//! Wasmer's WASI implementation
9//!
10//! Use `generate_import_object` to create an [`Imports`].  This [`Imports`]
11//! can be combined with a module to create an `Instance` which can execute WASI
12//! Wasm functions.
13//!
14//! See `state` for the experimental WASI FS API.  Also see the
15//! [WASI plugin example](https://github.com/wasmerio/wasmer/blob/main/examples/plugin.rs)
16//! for an example of how to extend WASI using the WASI FS API.
