#[derive(Clone)]
on a typestruct Foo<T>
adds an impl that requires thatT: Clone
:which is unfortunate in the case of senders, because we don't want to require that the items being sent are
Clone
for the channel sender to beClone
. This PR adds an explicitimpl Clone
for the bounded and unbounded sender types which does not have theT: Clone
bound.Note that this is also an issue with
#[derive(Debug)]
, but that one is harder to work around aschan::Tx
also has#[derive(Debug)]
, as doeschan::Chan
, so we'd have to add explicit impls for all of them to make progress.
