sealed abstract class NotUsed extends AnyRef

This type is used in generic type signatures wherever the actual value is of no importance. It is a combination of Scala’s Unit and Java’s Void, which both have different issues when used from the other language. An example use-case is the materialized value of an Akka Stream for cases where no result shall be returned from materialization.
