Struct Color 

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

RGBA color type.

all channels are normalized to the range 0.0 - 1.0. common colors are provided as associated constants.

example

let red = Color::rgb(1.0, 0.0, 0.0);
let semi_transparent = Color::rgba(1.0, 1.0, 1.0, 0.5);

Fields

r: f32

red channel (0.0 - 1.0)

g: f32

green channel (0.0 - 1.0)

b: f32

blue channel (0.0 - 1.0)

a: f32

alpha channel (0.0 - 1.0)

Implementations

impl Color

pub const BLACK: Self

pure black (0, 0, 0, 1).

pub const WHITE: Self

pure white (1, 1, 1, 1).

pub const RED: Self

pure red (1, 0, 0, 1).

pub const GREEN: Self

pure green (0, 1, 0, 1).

pub const BLUE: Self

pure blue (0, 0, 1, 1).

pub const TRANSPARENT: Self

fully transparent black (0, 0, 0, 0).

pub const fn rgb(r: f32, g: f32, b: f32) -> Self

create an RGB color with full opacity (alpha = 1.0).

pub const fn rgba(r: f32, g: f32, b: f32, a: f32) -> Self

create an RGBA color with explicit alpha.

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 Copy for Color

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.
