Struct AsyncioWaker

pub struct AsyncioWaker(GILOnceCell<Option<LoopAndFuture>>);

Available on crate feature experimental-async only.

Lazy asyncio.Future wrapper, implementing Wake by calling Future.set_result.

asyncio future is let uninitialized until initialize_future is called. If wake is called before future initialization (during Rust future polling), initialize_future will return None (it is roughly equivalent to asyncio.sleep(0))

Tuple Fields

0: GILOnceCell<Option<LoopAndFuture>>
