Since
IfWatcher
isUnpin
we can makepoll_next
take&mut self
instead ofself: Pin<&mut Self>
and implementStream
by usingPin::into_inner
.Proposed by @thomaseizinger in libp2p/rust-libp2p#2813 (comment).
@thomaseizinger did I understand it correctly that this was the idea?
Also renamed
poll_next
topoll_if_event
in e56e686 to avoid conflicting names with<IfWatcher as Stream>::poll_next
. I don't feel strongly about that, happy to drop that commit it if folks prefer to stick withpoll_next
.
