data Filler Source #

A meaningless sequence of 0 bits terminated with a 1 bit (easier to implement than the reverse) Useful to align an encoded value at byte/word boundaries.

fillerLength :: Num a => Filler -> a Source #

Length of a filler in bits

data PreAligned a Source #

A Pre aligned value, a value preceded by a filler Useful to prealign ByteArrays, Texts and any structure that can be encoded more efficiently when byte aligned.
