  6. final def compose[_O, _E >: E](that: stages.Evolution[O, _O, _E]): stages.Evolution[I, _O, _E]

    Composes this evolution with another, creating a new evolution whose continuation for any status is the sequential composition of the corresponding continuations of both evolutions.

    Composes this evolution with another, creating a new evolution whose continuation for any status is the sequential composition of the corresponding continuations of both evolutions.

    Specifically:

    composed(s) == self(s) ~> that(s)

    Used internally when merging evolutions during Yield composition inside Stage.AndThen.

    _O

    the output type of the resulting stages

    _E

    the combined error type

    that

    the downstream evolution to compose with

    returns

    a new evolution representing self followed by that

  7. def dispose(): Unit

    Releases all resources held by the Stage that produced this evolution.

    Releases all resources held by the Stage that produced this evolution.

    After this call the producing stage must be considered permanently unusable — it must not be applied or skipped again. This is the exclusive cleanup point for resources owned by the producing stage.

    Called when the producing stage is permanently shut down:

    • by Stage.execute after the pipeline has produced its terminal Outcome, so the continuation is released immediately rather than carried forward;
    • when apply throws a Throwable, since the stage can no longer be used and all its resources must still be released.

    Implementations that hold no external resources may leave this as a no-op.

    Returns the next Stage based on the given status.

    May release resources that are specific to this evolution instance and will not be reused by subsequent generations (i.e. resources not needed by the returned stage or its own evolution).

    status

    the status that determines the continuation stage

  14. final def map[_I, _O, _E](f: (Stage[I, O, E]) => Stage[_I, _O, _E]): stages.Evolution[_I, _O, _E]

    Transforms every continuation of this evolution by applying f to the stage it returns.

    This is the public API for adapting an Evolution to a different stage type without exposing internal composition details.

    _I

    the input type of the resulting stages

    _O

    the output type of the resulting stages

    _E

    the error type of the resulting stages

    f

    a function that transforms each continuation stage

    returns

    a new evolution with all continuations mapped by f
