Type Members

1. final class Accumulate[A, B] extends GraphStage[FlowShape[A, B]]

   

   This stage emits folded values like scan, but the first element emitted is not the zero value but the result of applying the given function to the given zero value and the first pushed element.

   B

2. type IndexedSeq[+A] = scala.collection.immutable.IndexedSeq[A]

   

3. type Iterable[+A] = scala.collection.immutable.Iterable[A]

   

4. final class LastElement[A] extends GraphStageWithMaterializedValue[FlowShape[A, A], Future[Option[A]]]

   

   This stage materializes to the last element pushed before upstream completion, if any, thereby recovering from any failure.

   This stage materializes to the last element pushed before upstream completion, if any, thereby recovering from any failure. Pushed elements are just passed along.
