Poll
implements theTry
trait, so we can use the?
operator andready!
macro to do the equivalent oftry_ready!
macro.Actually,
ready!
+?
operator is more powerful thantry_ready!
because it also can be used in functions that returnPoll<Option<Result>>
. (Also,Result
+?
can be used in functions that returnPoll<Result>
andPoll<Option<Result>>
as well.)I think it is not a problem to remove
try_ready!
, and it may also rather increase code consistency.Related: #1599, #1572
