Enum Equation

pub enum Equation {
    Add,
    Subtract,
    ReverseSubtract,
    Min,
    Max,
}

A blending equation.

Variants

Add

Add the source and destination, according to sp * S + dp * D.

Subtract

Subtract the destination from the source, according to sp * S - dp * D.

ReverseSubtract

Subtract the source from the destination, according to dp * D - sp * S.

Min

Create a color where each component is the smallest of each of the source and destination components. A.k.a. component wise min. The parameters are ignored.

Max

Create a color where each component is the largest of each of the source and destination components. A.k.a. component wise max. The parameters are ignored.

Trait Implementations

impl Clone for Equation

fn clone(&self) -> Equation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Equation

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

Formats the value using the given formatter.

impl PartialEq for Equation

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
