Type Members

  1. final class GroupBy[-R, +E, +K, +V] extends AnyRef

    Representation of a grouped stream.

    Representation of a grouped stream. This allows to filter which groups will be processed. Once this is applied all groups will be processed in parallel and the results will be merged in arbitrary order.

  2. type Pull[-R, +E, +A] = ZIO[R, Option[E], A]

    Describes an effectful pull from a stream.

    Describes an effectful pull from a stream. The optionality of the error channel denotes normal termination of the stream when None and an error when Some(e: E).
