Emit

zio.stream.ZStream$.Emit
trait Emit[+R, -E, -A, +B] extends ZIO[R, Option[E], Chunk[A]] => B

An Emit[R, E, A, B] represents an asynchronous callback that can be called multiple times. The callback can be called with a value of type ZIO[R, Option[E], Chunk[A]], where succeeding with a Chunk[A] indicates to emit those elements, failing with Some[E] indicates to terminate with that error, and failing with None indicates to terminate with an end of stream signal.
