final case class Widened[T, U >: T](behavior: Behavior[T], matcher: PartialFunction[U, T]) extends Behavior[U] with Product with Serializable
Widen the wrapped Behavior by placing a funnel in front of it: the supplied PartialFunction decides which message to pull in (those that it is defined at) and may transform the incoming message to place them into the wrapped Behavior’s type hierarchy. Signals are not transformed.

Process an incoming Signal and return the next behavior.
Process an incoming Signal and return the next behavior. This means that all lifecycle hooks, ReceiveTimeout, Terminated and Failed messages can initiate a behavior change.

narrow[U <: U]: Behavior[U]
Narrow the type of this Behavior, which is always a safe operation.
Narrow the type of this Behavior, which is always a safe operation. This method is necessary to implement the contravariant nature of Behavior (which cannot be expressed directly due to type inference problems).
