This commit starts wasm-bindgen down the path of supporting closures. We discussed this at the recent Rust All-Hands but I ended up needing to pretty significantly scale back the ambitions of what closures are supported. This commit is just the initial support and provides only a small amount of support but will hopefully provide a good basis for future implementations. Specifically this commit adds support for passing `&Fn(...)` to an *imported function*, but nothing elese. The `&Fn` type can have any lifetime and the JS object is invalidated as soon as the import returns. The arguments and return value of `Fn` must currently implement the `WasmAbi` trait, aka they can't require any conversions like strings/types/etc. I'd like to soon expand this to `&mut FnMut` as well as `'static` closures that can be passed around for a long time in JS, but for now I'm putting that off until later. I'm not currently sure how to implement richer argument types, but hopefully that can be figured out at some point! |
