Trait Signed 

pub trait Signed: Num + Neg<Output = Self> {
    const NEG_ONE: Self;

    // Required methods
    fn abs(x: Self) -> Self;
    fn signum(x: Self) -> Self;
}

A signed primitive number type.

Required Associated Constants

const NEG_ONE: Self

Required Methods

fn abs(x: Self) -> Self

Computes the absolute value of the number.

fn signum(x: Self) -> Self

Returns the sign of the number, or 0 if the number is 0.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
