Documentation
topNBits :: Int -> Word8 Source #
This is used for masking the last byte of a ByteString so that extra bits don't leak in
bottomNBits :: Int -> Word8 Source #
Return a Word8 with the bottom n bits set
leftShift :: Int -> ByteString -> ByteString Source #
Shift the whole ByteString some number of bits left where 0 <= n < 8
rightShift :: Int -> ByteString -> ByteString Source #
Shift the whole ByteString some number of bits right where 0 <= n < 8
leftTruncateBits :: Int -> ByteString -> ByteString Source #
Truncate a ByteString to a given number of bits (counting from the left) by masking out extra bits in the last byte
rightTruncateBits :: Int -> ByteString -> ByteString Source #
Truncate a ByteString to a given number of bits (counting from the right) by masking out extra bits in the first byte
