object AskPattern

The ask-pattern implements the initiator side of a request–reply protocol. The party that asks may be within or without an Actor, since the implementation will fabricate a (hidden) ActorRef that is bound to a scala.concurrent.Promise. This ActorRef will need to be injected in the message that is sent to the target Actor in order to function as a reply-to address, therefore the argument to the ask / ? operator is not the message itself but a function that given the reply-to address will create the message.

case class Request(msg: String, replyTo: ActorRef[Reply])
case class Reply(msg: String)

implicit val timeout = Timeout(3.seconds)
val target: ActorRef[Request] = ...
val f: Future[Reply] = target ? (Request("hello", _))
