コントラクト

• FuturesOrdered executes queued futures concurrently but yields completed items strictly in the order they were pushed, returning Poll::Pending when successor futures finish before preceding ones and buffering their results for immediate subsequent delivery once predecessor futures complete.
• Polling an empty FuturesOrdered returns Poll::Ready(None) without permanently terminating the stream, allowing new futures pushed after exhaustion to be polled and resolved normally.
• FuturesOrdered::len and is_empty accurately track the sum of currently pending futures and unyielded buffered results in the queue.
