Crate wasmer_wasi_fl 

Wasmer’s WASI implementation

Use generate_import_object to create an ImportObject. This ImportObject can be combined with a module to create an Instance which can execute WASI Wasm functions.

See state for the experimental WASI FS API. Also see the WASI plugin example for an example of how to extend WASI using the WASI FS API.
