CTEq	Trait for items whose equality to another item may be tested in constant time.
CTNegatable	Trait for items which can be conditionally negated in constant time.

arrays_equal	Check equality of two arrays, `a` and `b`, in constant time.
byte_is_nonzero	Test if a byte is non-zero in constant time.
bytes_equal	Check equality of two bytes in constant time.
conditional_select	Select `a` if `choice == 1` or select `b` if `choice == 0`, in constant time.
