+modules produced from Rust crates. Hence, while not technically a requirement to
+compile ngx_wasm_module or to produce Wasm bytecode, having Rust installed on

 - [rustup.rs](https://rustup.rs/) is the easiest way to install Rust.
     - Then add the Wasm target to your toolchain: `rustup target add
       wasm32-unknown-unknown`.
     - As well as the [WASI](https://wasi.dev/) target: `rustup target add
       wasm32-wasi`.
