deltaParse :: Parser ByteString Delta #

parse a delta. format is 2 variable sizes, followed by delta cmds. for each cmd: * if first byte MSB is set, we copy from source. * otherwise, we copy from delta. * extensions are not handled.

deltaRead :: ByteString -> Maybe Delta #

read one delta from a lazy bytestring.

deltaApply :: ByteString -> Delta -> ByteString #

apply a delta on a lazy bytestring, returning a new bytestring.
