- xlisten(+Redis, +Streams, +OnBroadCast, +OnIdle, +Options)[private]
- Generalized version of xlisten/3 that is provided two callbacks: one
to handle a message and one after each time the underlying
XREADGROUPhas returned and the messages are processed. These callbacks are called as follows:
call(OnBroadCast, +Redis, +Stream, +MessageId, +Dict) call(OnIdle, +Redis, +Streams, +Starts, +NewStarts, +Options)
Both callbacks must succeeds and not leave any open choice points. Failure or exception causes xlisten/5 to stop.
