bitset-word8

License: MIT Build Status Hackage

Space efficient set of Word8 and some pre-canned sets useful for parsing HTTP related ByteString. This packaged is intended to provide O(1) membership test on any subset of ASCII and Latin-1 character set in order to write efficient HTTP related parser.

Creating your own set

You can create your own set by fromList.

myCharSet :: BitSetWord8
myCharSet = fromList [ 'Y', 'y', 'N', 'n' ]

You can create pre-evaluated set using Template Haskell.

{-# LANGUAGE TemplateHaskell #-}
import Language.Haskell.TH.Syntax (Lift, lift)

myPreEvaluatedCharSet :: BitSetWord8
myPreEvaluatedCharSet = $(lift myCharSet)
