Trait Signed

pub trait Signed: PartialOrd + Zero {
    // Required methods
    fn positive(&self) -> bool;
    fn negative(&self) -> bool;
    fn non_negative(&self) -> bool;
    fn non_positive(&self) -> bool;
}

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

Required Methods

fn positive(&self) -> bool

If this element is strictly greater than zero

fn negative(&self) -> bool

If this element is strictly less than zero

fn non_negative(&self) -> bool

If this element is greater than or equal to zero

fn non_positive(&self) -> bool

If this element is less than or equal to zero

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.

Implementors

impl<G: PartialOrd + Zero> Signed for G

Auto-implemented using default to allow for specialization if desired
