Implement `RawWaker` and `Waker` getters for underlying pointers implement #87021 New APIs: - `RawWaker::data(&self) -> *const ()` - `RawWaker::vtable(&self) -> &'static RawWakerVTable` - ~`Waker::as_raw_waker(&self) -> &RawWaker`~ `Waker::as_raw(&self) -> &RawWaker` This third one is an auxiliary function to make the two APIs above more useful. Since we can only get `&Waker` in `Future::poll`, without this, we need to `transmute` it into `&RawWaker` (relying on `repr(transparent)`) in order to access its data/vtable pointers. ~Not sure if it should be named `as_raw` or `as_raw_waker`. Seems we always use `as_<something-raw>` instead of just `as_raw`. But `as_raw_waker` seems not quite consistent with `Waker::from_raw`.~ As suggested in https://github.com/rust-lang/rust/pull/91828#discussion_r770729837, use `as_raw`. |
