I have honestly no idea what you're saying isn't possible. I've been writing a bunch of Rust code running in browsers, for work and play. I'm not futzing with the details, I just use wasm-bindgen and web-sys. I've honestly never worried about garbage collection before, one of the professional hazards of working with a well-designed Rust API. I guess that web-sys provides types with a Drop impl that tell the browser side the object is dead. > without having to manually mark as held and free. I guess that's what you're worried about? It's never been a concern of mine. Maybe if one were writing WASM by hand?
