| * @assertion Future done |
| * Return a future which is completed when the StreamSink is finished. |
| * |
| * If the StreamSink fails with an error, perhaps in response to adding events |
| * using add, addError or close, the done future will complete with that error. |
| * |
| * Otherwise, the returned future will complete when either: |
| * - all events have been processed and the sink has been closed, or |
| * - the sink has otherwise been stopped from handling more events (for |
| * example by cancelling a stream subscription). |
| * |
| * @description Checks that if synchronous methods resulted in no errors, |
| * done completes with the same value as close(). |
