// An alteration converts any Stage to a (possibly different) Stage:

Type Members

  1. final case class AndThen[-I, OI, +O, +E](upstream: Stage[I, OI, E], downstream: Stage[OI, O, E]) extends Stage[I, O, E] with Product with Serializable

    A Stage composed of two sequential stages.

    A Stage composed of two sequential stages.

    When applied to an input:

    • If upstream produces a Yield.Some, the output is passed to downstream.
    • If upstream produces a Yield.None, the evolution is composed with downstream so that it is applied when the pipeline resumes.
    I

    input type of the pipeline

    OI

    intermediate type between the two stages

    O

    output type of the pipeline

    E

    error type

    upstream

    the first stage in the sequence

    downstream

    the second stage in the sequence

  2. type Any = Stage[_, _, _]

    An existential alias for a stage with unknown type parameters, useful as a common supertype.

  3. type Endo[T, +E] = Stage[T, T, E]

    A stage whose input and output types are the same — an endomorphism on T.
