Trait Signed 

pub trait Signed:
    Num
    + Neg<Output = Self>
    + PartialOrd {
    // Required methods
    fn abs(self) -> Self;
    fn signum(self) -> Self;
    fn is_negative(self) -> bool;
}

Signed numbers: negation, absolute value, sign.

Required Methods

fn abs(self) -> Self

Absolute value.

fn signum(self) -> Self

-1, 0, or +1.

fn is_negative(self) -> bool

Returns true if the number is negative.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
