Enum Signum 

pub(crate) enum Signum {
    Negative = -1,
    Zero = 0,
    Positive = 1,
}

The sign of a number (mathematically, sgn(x)). Although in a one’s-complement system all values have a sign, we treat zero specially in order to simplify working with native types and one’s-complement types together.

Variants

Negative = -1

Zero = 0

Positive = 1
