member :: BitSetWord8 -> Word8 -> Bool

O(1). Return True if given Word8 is a member of given BitSetWord8.

toWord8Set :: [Char] -> Set Word8

Convert given list of Char into Set of Word8. Any Char having code point greater than 0xff is ignored.

toBoolList :: Set Word8 -> [Bool]

Convert Set of Word8 to full filled list of boolean existence flag.

toWord8 :: [Bool] -> Word8

Pack 8 of boolean list into single Word8 bitwise set.

toWord8List :: [Bool] -> [Word8]

Convert full filled boolean list into 32 packed Word8 list.

fromList :: [Char] -> BitSetWord8
