Struct deltae::DeltaE

pub struct DeltaE {
    pub method: DEMethod,
    pub value: f32,
}

The measured difference between two colors

There are many different methods of calculating color difference. Different methods have a specific purpose, mainly in determining the level of tolerance for describing the difference between two colors.

Fields

method: DEMethod

The mathematical method used for calculating color difference

value: f32

The calculated value

Methods

impl DeltaE

pub fn new<A, B>(a: A, b: B, method: DEMethod) -> DeltaE where
    A: Delta,
    B: Delta, 

New DeltaE from colors and DEMethod.

Trait Implementations

impl Round for DeltaE

fn round_to(self, places: i32) -> Self

Rounds the value to a number of decimal places

impl PartialOrd<DeltaE> for DeltaE

One should be careful when ordering DeltaE. A DE2000:1.0 value is not necessarily the same amount of color difference as a amount of color difference DE1976:1.0 value.

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Clone for DeltaE

fn clone(&self) -> DeltaE

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq<DeltaE> for DeltaE

fn eq(&self, other: &DeltaE) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DeltaE) -> bool

This method tests for !=.

impl PartialEq<f32> for DeltaE

fn eq(&self, f: &f32) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Copy for DeltaE

impl Display for DeltaE

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Debug for DeltaE

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
