final class With[T] extends DIStageAnnotation

This annotation lets you choose a more specific implementation for a result of factory method other than its return type.

Example:

 trait Actor {
   def id: UUID
 }

 trait ActorFactory {
   @With[ActorImpl]
   def newActor(id: UUID): Actor
 }

 class ActorImpl(val id: UUID, someDependency: SomeDependency) extends Actor
 class SomeDependency

 val module = new ModuleDef {
   make[ActorFactory]
   // generated factory implementation:
   //
   // make[ActorFactory].from {
   //  (someDependency: SomeDependency) =>
   //    new ActorFactory {
   //      override def newActor(id: UUID): Actor = {
   //        new ActorImpl(id, someDependency)
   //      }
   //    }
   // }
 }
