trait ZStreamChunk[-R, +E, +A] extends AnyRef

A ZStreamChunk[R, E, A] represents an effectful stream that can produce values of type A, or potentially fail with a value of type E.

ZStreamChunk differs from ZStream in that elements in the stream are processed in batches, which is orders of magnitude more efficient than dealing with each element individually.

ZStreamChunk is particularly suited for situations where you are dealing with values of primitive types, e.g. those coming off a java.io.InputStream
