Description |
|---|---|---|
|
work |
Promise<U> |
the promise to wait for |
|
message |
any |
(Optional) the popped message, for job handling only; a drain that runs out of budget puts this back on the queue |
Returns:
Promise<U>
work, unchanged
Remarks
Bookkeeping attaches to a *derived* promise, never to work itself, so a rejection stays whoever owns it to handle and this can never become an unhandled rejection of its own.
A no-op that allocates nothing when draining is off, which is what keeps the default path exactly what it was.
