ActorModule

Facilitates runtime dependency injection of "functional programming"-style actor behaviors.

1. Mix this trait into the object defining the actor message(s) and behavior(s);
2. Define the Message type with actor message class;
3. Annotate with Provides the "create" method that returns the (possibly just initial) Behavior of the actor;
4. Use the bindTypedActor in PekkoGuiceSupport, passing the object as the actor module.

For example:

 object ConfiguredActor extends ActorModule {
   type Message = GetConfig

   final case class GetConfig(replyTo: ActorRef[String])

   @Provides def apply(configuration: Configuration): Behavior[GetConfig] = {
     // TODO: Define ConfiguredActor's behavior using the injected configuration.
     Behaviors.empty
   }
 }

 final class AppModule extends AbstractModule with PekkoGuiceSupport {
   override def configure() = {
     bindTypedActor(ConfiguredActor, "configured-actor")
   }
 }

Message is a type member rather than a type parameter is because you can't define, using the example above, GetConfig inside the object and also have the object extend ActorModule[ConfiguredActor.GetConfig].
