Follow-up on #962
Before
futures channels
were used andis_closed
can't be implemented and I introduced a bug by cloning the sender which forces the subscription never to returnNone
as it is the same channel which is used in the subscription.Thus, just remove
is_closed
and one have to useasync fn next()
to determine whether a subscription is closed.
