One thing articles like this always miss, and what I'm most keen on, is how exactly the bridging works. Is there a standard Rust wasm crate that exposes the DOM? Do you pass some struct with function pointers? Is the Rust code exposed as a black box with no connection to the outside world and you just call a few entrypoint functions? Can you call Rust from JS and JS from Rust? If you go JS->Rust->JS->Rust->JS and the innermost JS function throws an exception, is all that properly propagated up the stack?
