PatchbayJobCancellation typedef
PatchbayJobCancellation =
FutureOr<void> Function()
Confirms that the underlying operation has stopped after cancellation.
Returning after merely sending a cancellation request would let the
registry publish a false terminal state. Consumers without confirmation
must omit this callback and report the real terminal state from body.
Implementation
