Off the top of my head: not sure how you are getting the parameters, if
any, to getNextItem, but since xxAsync methods like Source.unfoldAsync and
mapAsync expect a future-returning function, I would use getNextItem
(rather than identity) in one of those to give you downstream elements of
type
Hi,
What is the correct way to create a source from a function which returns
Future[Option[A]], besides a custom GraphStage?
The source should emit A elements (not wrapped in Future[Option[]]).
I considered a few options, none of them worked
