          def ExecutionLogIterator.done() -> bool
Returns `True` once the stream has ended and every entry has been received via `for` or repeated `try_pop`, or the subscriber has been released (`build.wait()`). `function` **ExecutionLogIterator.drain** 
        
          def ExecutionLogIterator.drain() -> None
Stop consuming: unsubscribe and drop whatever is buffered. Idempotent. As on an \[`ExecLogIter`] handle — a task that decides mid-build it no longer wants entries releases the producer's blocking-send path rather than holding the end-of-build join open until `wait()` does it. `function` **ExecutionLogIterator.try\_pop** 
        
          def ExecutionLogIterator.try\_pop() -> None | exec\_log\_entry
Non-blocking pop of the next entry, or `None` when nothing is buffered yet. The producer runs up to the channel capacity ahead and then waits for this subscriber, so polling slowly costs time rather than entries.
