Build Status

Haskell implementation of the Consistent Overhead Byte Stuffing algorithm.

It provides a Stuffed newtype wrapper for Lazy Bytestrings, which is parametrized on the Byte (Word8, represented as a type-level Nat) to be encoded away.

The implementation tries to be as efficient as possible, type safe and easy to use. If you have a "sink" like

sink :: Stuffed 0 -> IO ()
sink = undefined

You'd then simply be able to encode a Bytestring with sink $ stuff bytes.

You can try this out in ghci with:

> :set -XOverloadedStrings
> :set -XDataKinds
> import Data.Stuffed
> let stuffedBytes = stuff "a\0b\0c" :: Stuffed 0
> unpack $ unwrap stuffedBytes -- directly access the underlying bytestring
[2,97,2,98,2,99]
> unpack $ unstuff stuffedBytes
[97,0,98,0,99]
