Polling an empty FuturesUnordered returns None without terminating the collection so new futures can be pushed and polled dynamically, whereas wrapping it in Fuse permanently latches is_terminated on the first None and ignores subsequent pushed tasks

Contrat

• assert polling an empty FuturesUnordered returns Ready(None) without preventing subsequent push calls from yielding new items on future polls
• assert wrapping FuturesUnordered in Fuse permanently latches is_terminated on the first None and returns Ready(None) forever even when new items are pushed to the inner queue
• assert buffer_unordered with zero capacity returns Poll::Pending unconditionally without draining available items from the upstream stream
• assert polling select_next_some on an already terminated fused stream panics at runtime while next returns Ready(None)
• assert ready_chunks yields all currently available elements immediately in a single poll batch without waiting for the full capacity buffer or stream EOF
• assert SplitSink::reunite only succeeds when paired with the SplitStream from the same split invocation and fails on cross-split pairs
• assert stream select exhausts both constituent streams completely before returning Ready(None)
