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.
