Class NotUsed

  • Direct Known Subclasses:

    public abstract class NotUsed
    extends java.lang.Object
    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 a Pekko Stream for cases where no result shall be returned from materialization.
