abstract class Mapper[-T, +R] extends AbstractFunction1[T, R]

Callback for the Future.map and Future.flatMap operations that will be invoked if the Future that this callback is registered on becomes completed with a success. This callback is the equivalent of an akka.japi.Function

Override "apply" normally, or "checkedApply" if you need to throw checked exceptions.

  6. def unlift: PartialFunction[T, B]
    Implicit
    This member is added by an implicit conversion from Mapper[T, R] toUnliftOps[T, B] performed by method UnliftOps in scala.Function1.This conversion will take place only if R is a subclass of Option[B] (R <: Option[B]).
