valueconstEqBytes :: Byteable a => a -> a -> Bool

Source#

A constant time equality test for 2 byteable objects.

If objects 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.
