Site deprecation, check out RustWasm- Jan-Erik Rediger
This site hasn't been updated in over a year. Since then a lot of stuff happened in Rust and the WebAssembly world.
The Rust and WebAssembly working group was founded and now provides a lot of tooling, documentation, tutorials and other material. For a complete introduction to Rust and WebAssembly check out the Rust 🦀 and WebAssembly 🕸 book.
