Simple Rust Program in WebAssembly

This guide does not cover the details of Rust or its installation. Since Rust is LLVM-based, it theoretically only needs a backend for WebAssembly. The backend is included in the Rust standard library.

If LLVM is new or there is further interest in the topic, I recommend consulting my previous posts:

• Simple C Program in WebAssembly provides an introduction to LLVM, among other things.
• First Experiences with WebAssembly already uses wasm3 in a REPL-style.
