Description

Fast set membership tests for byte values. The set representation is unboxed for efficiency and uses one bit per byte to represent the presence or absence of a byte in the set.

This is a fairly minimal API. You probably want to use CharSet.

Synopsis

newtype ByteSet = ByteSet ByteString
fromList :: [Word8] -> ByteSet
member :: Word8 -> ByteSet -> Bool
