Ask

cc.otavia.core.message.Ask

trait Ask[R <: Reply] extends Call

A Call that expects a reply of type R. When an actor receives an Ask, it must eventually call stack.return(reply) to deliver a R back to the sender.

The match type ReplyOf extracts R from an Ask at compile time, enabling type-safe request-response patterns without manual casting:

case class GetUser(id: Long) extends Ask[User]
// ReplyOf[GetUser] resolves to User at compile time

Type parameters

R: the expected reply type
