Trait Sign

pub trait Sign: Signed {
    // Required methods
    fn signum(self) -> Self;
    fn abs(self) -> Self;
}

Helpful methods for manipulating an element’s order relative to 0

Required Methods

fn signum(self) -> Self

Returns 1 if positive, -1 if negative, or itself (ie. 0 or NaN) if neither

fn abs(self) -> Self

Returns this element’s negative if less than 0 or itself otherwise

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.
