struct DeferredDropReport(Option<(String, Arc<Mutex<PersistentInner>>)>);Expand description
The last line of defence for §4.5: whatever is still deferred when the controller goes away is reported, not silently discarded with it.
stop() and shutdown() drain the queue, but a sender that fetched the
controller before it was unregistered can still enqueue after that drain
(codex P2 on #3562). The watchdog holds only a weak reference, so it dies
with the controller and cannot catch it. stop() cannot refuse those late
senders instead: the max-runtime watchdog stops controllers that stay
registered and get used again.
A field rather than Drop on the controller itself, so struct-update
construction (..c, used throughout the tests) keeps working. Holds the
controller’s own inner; None only transiently inside new().
