This package contains experimental WASI API bindings in Rust.
There are two modules:
wasi_unstable::raw, which provides raw access to the literal binding to the API. These functions are unsafe and use raw pointers.
wasi_unstable, which provides thin wrappers around the raw functions which use idiomatic Rust types rather than raw pointers, and are safe.
This crate is quite low-level and provides conceptually a “system call” interface. In most settings, it's better to use the Rust standard library, which has WASI support.
To compile Rust projects to wasm using WASI, use the wasm32-wasi target, like this:
rustup target add wasm32-wasi cargo build --target wasm32-wasi
