Description

Fast set membership tests for byte values, The set representation is unboxed for efficiency and uses a lookup table. This is a fairly minimal API. You probably want to use CharSet.

Synopsis

Data type

newtype ByteSet #

Constructors

ByteSet ByteString

Show ByteSet #
Methods showsPrec :: Int -> ByteSet -> ShowS # show :: ByteSet -> String # showList :: [ByteSet] -> ShowS #

Construction

fromList :: [Word8] -> ByteSet #

Lookup

member :: Word8 -> ByteSet -> Bool #

Check the set for membership.
