Trait RealInstance 

pub trait RealInstance:
    PartialEq
    + PartialOrd
    + Sized {
    const ONE: Self;
    const ZERO: Self;

    // Provided methods
    fn is_positive(&self) -> bool { ... }
    fn is_negative(&self) -> bool { ... }
    fn is_zero(&self) -> bool { ... }
}

Defines common operations on real (i.e. not Complex) numbers.

Required Associated Constants

const ONE: Self

const ZERO: Self

Provided Methods

fn is_positive(&self) -> bool

Return true if this is zero or a positive number.

fn is_negative(&self) -> bool

Return true if this is a negative number.

fn is_zero(&self) -> bool

Return true if this is 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.
