bitset-word8
Space efficient set of Word8 and some pre-canned sets useful for parsing HTTP related ByteString.
This package 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)
Example Usage
import Data.Attoparsec.ByteString
-- | Parse RFC7230 token.
token :: Parser ByteString
token = takeWhile1 (member rfc7230TChar)
