Function futures_util::task::local_waker_ref

pub unsafe fn local_waker_ref<W>(wake: &Arc<W>) -> LocalWakerRef where
    W: Wake + 'static, 

Creates a reference to a LocalWaker from a local wake.

Safety

This function requires that wake is "local" (created on the current thread). The resulting LocalWaker will call wake.wake_local() when awoken, and will call wake.wake() if awoken after being converted to a Waker.
