default null compression

datadata NullCompression

This is the default compression which is a NOOP.

member redefined for the class abstraction

valuecompressionID :: Compression -> CompressionID

return the associated ID for this algorithm

valuecompressionDeflate :: ByteString -> Compression -> (Compression, ByteString)

deflate (compress) a bytestring using a compression context and return the result along with the new compression context.

valuecompressionInflate :: ByteString -> Compression -> (Compression, ByteString)

inflate (decompress) a bytestring using a compression context and return the result along the new compression context.

helper

valuecompressionIntersectID :: [Compression] -> [Word8] -> [Compression]

intersect a list of ids commonly given by the other side with a list of compression the function keeps the list of compression in order, to be able to find quickly the preferred compression.
