Expand description
A macro which returns the result of polling a future once within the
current async
context.
This macro is only usable inside of async
functions, closures, and blocks.
It is also gated behind the async-await
feature of this library, which is
activated by default.
If you need the result of polling a Stream
,
you can use this macro with the next
method:
poll!(stream.next())
.
