* Tweak the implementation of heap closures This commit updates the implementation of the `Closure` type to internally store an `Rc` and be suitable for dropping a `Closure` during the execution of the closure. This is currently needed for promises but may be generally useful as well! * Support asynchronous tests This commit adds support for executing tests asynchronously. This is modeled by tests returning a `Future` instead of simply executing inline, and is signified with `#[wasm_bindgen_test(async)]`. Support for this is added through a new `wasm-bindgen-futures` crate which is a binding between the `futures` crate and JS `Promise` objects. Lots more details can be found in the details of the commit, but one of the end results is that the `web-sys` tests are now entirely contained in the same test suite and don't need `npm install` to be run to execute them! * Review tweaks * Add some bindings for `Function.call` to `js_sys` Name them `call0`, `call1`, `call2`, ... for the number of arguments being passed. * Use oneshots channels with `JsFuture` It did indeed clean up the implementation!
