Macros

join
pending	A macro which yields to the event loop once. This is similar to returning Poll::Pending from a Future::poll implementation. If pending! is used, the current task should be scheduled to receive a wakeup when it is ready to make progress.
pin_mut	Pins a value on the stack.
poll	A macro which returns the result of polling a future once within the current async context.
ready	Extracts the successful type of a Poll<T>.
select
try_poll	Extracts Poll<T> from Poll<Result<T, E>>.
try_ready	Extracts the successful type of a Poll<Result<T, E>>.
unsafe_pinned	A pinned projection of a struct field.
unsafe_unpinned	An unpinned projection of a struct field.
