cons package:memory

cons :: ByteArray a => Word8 -> a -> a
memory Data.ByteArray
prepend a single byte to a byte array
cons :: forall ni no bi bo . (ByteArrayN ni bi, ByteArrayN no bo, ByteArrayAccess bi, KnownNat ni, KnownNat no, (ni + 1) ~ no) => Word8 -> bi -> bo
memory Data.ByteArray.Sized
prepend a single byte to a byte array
constEq :: (ByteArrayAccess bs1, ByteArrayAccess bs2) => bs1 -> bs2 -> Bool
memory Data.ByteArray
A constant time equality test for 2 ByteArrayAccess values. If values are of 2 different sizes, the function will abort early without comparing any bytes. compared to == , this function will go over all the bytes present before yielding a result even when knowing the overall result early in the processing.
uncons :: ByteArray a => a -> Maybe (Word8, a)
memory Data.ByteArray
returns the first byte, and the remaining bytearray if the bytearray is not null
memConstEqual :: Ptr Word8 -> Ptr Word8 -> Int -> IO Bool
memory Data.Memory.PtrMethods
A constant time equality test for 2 Memory buffers compared to normal equality function, this function will go over all the bytes present before yielding a result even when knowing the overall result early in the processing.
