Trait const_linear::traits::Scalar

pub trait Scalar: Ops<Self> {
    const ZERO: Self;
    const ONE: Self;

    fn to_f64(self) -> f64;
    fn to_f32(self) -> f32;
}

A value which has some sensible notion of arithmetic, a Debug implementation, and is Copy. This trait is sealed, and can not be implemented outside of const_linear.

Examples

One and Zero values

use const_linear::traits::Scalar;

let x = i32::ZERO;
let y = i32::ONE;

assert_eq!(x - y, -1);

Converting to floating point

use const_linear::traits::Scalar;

assert_eq!(1.to_f64(), 1 as f64);
assert_eq!(1.to_f32(), 1 as f32);

Associated Constants

const ZERO: Self

The "zero" value for this Scalar type. Acts as the additive identity.

const ONE: Self

The "one" value for this Scalar type. Acts as the multiplicative identity.
