Trait relp_num::NonZeroSigned

pub trait NonZeroSigned: NonZero + Clone {
    fn signum(&self) -> NonZeroSign;

    fn is_positive(&self) -> bool { ... }
    fn is_negative(&self) -> bool { ... }
}

A signed number that can have a nonzero value.

Required methods

fn signum(&self) -> NonZeroSign

Whether the value is positive or negative.

Provided methods

fn is_positive(&self) -> bool

Whether x > 0.

fn is_negative(&self) -> bool

Whether x < 0.
