Motivation
I sometimes find it useful to pass
SocketRef
across threads.However, I need to use
Arc<SocketRef>
to do that despite thatSocketRef
itself is essentially anArc
.SocketIo
which also wrapsArc
already hasclone
method. So I believe that we can haveSocketRef::clone
too.Solution
This PR implements the
Clone
trait forSocketRef
likeSocketIo
.
