awaken-0.3.0 has been yanked.
Provides a Waker trait to allow using the Waker from mio or a provided
Waker that uses eventfd directly (supported only on linux) interchangably.
This is particularly useful in cases where some struct (such as a queue) may
be used with either mio-based event loops, or with io_uring. The Waker
provided by mio is not directly usable in io_uring based code due to the
fact that it must be registered to an event loop (such as epoll).
