Type Aliases

The ZStream data type, has two type aliases:

type Stream[+E, +A] = ZStream[Any, E, A]
type UStream[+A]    = ZStream[Any, Nothing, A]

  1. Stream[E, A] is a type alias for ZStream[Any, E, A], which represents a ZIO stream that does not require any services, and may fail with an E, or produce elements with an A.

  2. UStream[A] is a type alias for ZStream[Any, Nothing, A], which represents a ZIO stream that does not require any services, it cannot fail, and after evaluation, it may emit zero or more values of type A.
