Synopsis

Documentation

packedBytes :: IsByteString t => Lens' [Word8] t Source #

Treat a list of bytes as a strict or lazy ByteString.

unpackedBytes :: IsByteString t => Lens' t [Word8] Source #

Treat a strict or lazy ByteString as a list of bytes.

packedChars :: IsByteString t => Lens' String t Source #

Treat a String as a strict or lazy ByteString. (Note that it will garble characters above 0xFF, same as pack does.)

unpackedChars :: IsByteString t => Lens' t String Source #

Treat a strict or lazy ByteString as a String. (Just as packedChars, it will garble characters above 0xFF.)

chars :: IsByteString t => Traversal' t Char Source #

Traverse characters in a strict or lazy ByteString (to traverse bytes instead of characters, use each).
