What is Webassembly?
Part : Webassembly and Rust
The appeal of looking at Rust in light of WASM over C or C++ is that it has native compilation without needing Emscripten.
Here: https://github.com/rust-lang/rust/pull/45905 is the project to add that.
This is a project to facilitate front-end Rust work so I would expect them to stay on top of providing an up-to-date summary of how to get started.
