Struct Color 

pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

sRGB color with alpha, stored as four f32 channels in [0.0, 1.0].

Uses straight (non-premultiplied) alpha. Conversion to premultiplied happens at the rendering boundary when handing off to the GPU.

Fields

r: f32

g: f32

b: f32

a: f32

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl Default for Color

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Color

fn eq(&self, other: &Color) -> 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.

impl Copy for Color

impl StructuralPartialEq for Color
