Create a org.reactivestreams.Publisher backed by a ActorPublisher actor.
Create a org.reactivestreams.Publisher backed by a ActorPublisher actor. It can be attached to a org.reactivestreams.Subscriber or be used as an input source for a akka.stream.scaladsl.Flow.
(Since version 2.5.0) Use
akka.stream.stage.GraphStage
instead, it allows for all operations an Actor would and is more type-safe as well as guaranteed to be ReactiveStreams compliant.
