trait ZSink[-R, +E, +A0, -A, +B] extends AnyRef

A Sink[E, A0, A, B] consumes values of type A, ultimately producing either an error of type E, or a value of type B together with a remainder of type A0.

Sinks form monads and combine in the usual ways.

    Runs both sinks in parallel on the same input.

    Runs both sinks in parallel on the same input. If the left one succeeds, its value will be produced. Otherwise, whatever the right one produces will be produced. If the right one succeeds before the left one, it accumulates the full input until the left one fails, so it can return it as the remainder.
