Trait DeltaE

pub trait DeltaE {
    type Scalar;

    // Required method
    fn delta_e(self, other: Self) -> Self::Scalar;
}

Calculate the ΔE color difference between two colors.

This represents the original ΔE formula for a color space. It’s often a Euclidean distance for perceptually uniform color spaces and may not always be the best option. See the color_difference module for more details and options.

Required Associated Types

type Scalar

The type for the distance value.

Required Methods

fn delta_e(self, other: Self) -> Self::Scalar

Calculate the ΔE color difference metric for self and other, according to the color space’s specification.

Object Safety

This trait is not object safe.
