O(n) map f xs is the ByteStream obtained by applying f to each element of xs.
O(n) map f xs is the ByteStream obtained by applying f to each element of xs.
Instead of mapping over each Word8 or Char, map over each strict ByteString chunk in the stream.
Like chunkMap, but map effectfully.
Like chunkMapM, but discard the result of each effectful mapping.
