Trait numerics::SignedAndUnsigned

pub trait SignedAndUnsigned: Sized {
    const MINIMUM: Self;

    fn abs(&self) -> Option<Self>;
    fn is_negative(&self) -> bool;
}

Signed number operations implemented for both signed and unsigned numbers.

Associated Constants

const MINIMUM: Self

Minimum value for the type.

Required methods

fn abs(&self) -> Option<Self>

The absolute value of a number. If the number is signed and equal to ::MIN, this operation would normally panic at overflow in debug or return ::MIN in release. This is undesired behavior, so we return None instead.

fn is_negative(&self) -> bool

Reports whether the number is negative.
