Saturating subtraction. Compute self - rhs, saturating at the numeric bounds instead of overflowing.

fn saturating_mul(self, rhs: Self) -> Self

Saturating multiply. Compute self * rhs, saturating at the numeric bounds instead of overflowing.

fn saturating_pow(self, exp: usize) -> Self

Saturating exponentiation. Compute self.pow(exp), saturating at the numeric bounds instead of overflowing.
