This PR adds analogues to the methods of all the stream/sink combinators which allow accessing the thing being wrapped. Here it lets you access the iterator, which is currently not possible.
I'm intentionally not using the
delegate_access_inner
macro, because the doc comments describe the inner member as being a stream or sink, which it is not forIter
(it also requires usingpin_project
, whichIter
does not do or need).
