Using the async is how it should be done, you should never use Await or call the internal methods of the GraphStageLogic from another thread as you do in your sample code.
Create the async callback in the onPush method though, not inside the future onComplete callback. You can let the callback accept a Try[YourThing] and do the pattern matching on the success/failure there and then just use pass the invoke method as parameter to Future.onComplete. -- Johan Akka Team On Sun, Aug 6, 2017 at 12:34 AM, Gary Struthers <[email protected]> wrote: > GraphStageLogic has getAsyncCallback.
