unfoldM package:streaming-bytestring

O(n) The unfoldM function is analogous to the Stream unfoldr. unfoldM builds a ByteStream from a seed value. The function takes the element and returns Nothing if it is done producing the ByteStream or returns Just (a,b), in which case, a is a prepending to the ByteStream and b is used as the next element in a recursive call.

cycle ties a finite ByteStream into a circular one, or equivalently, the infinite repetition of the original ByteStream. | O(n) The unfoldM function is analogous to the Stream 'unfoldr'. unfoldM builds a ByteStream from a seed value. The function takes the element and returns Nothing if it is done producing the ByteStream or returns Just (a,b), in which case, a is a prepending to the ByteStream and b is used as the next element in a recursive call.

Given some continual monadic action that produces strict ByteString chunks, produce a stream of bytes.
