Trait OverflowingNeg

pub trait OverflowingNeg {
    type Output;

    // Required method
    fn overflowing_neg(self) -> (Self::Output, bool);
}

Negates a number.

Returns a tuple of the sum along with a boolean indicating whether an arithmetic overflow occurred. If an overflow occurred, then the wrapped number is returned.
