Struct Color 

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

An sRGB color with alpha.

Fields

r: u8

g: u8

b: u8

a: u8

Implementations

impl Color

pub const CLEAR: Color

All black with no alpha

pub const fn rgba(r: u8, g: u8, b: u8, a: u8) -> Color

Create a new Color.

pub const fn rgb(r: u8, g: u8, b: u8) -> Color

Create a new Color with full opacity.

pub const fn hex(value: u32) -> Color

Create a color from a number, intended to be written as a hex literal.

let orange = Color::hex(0xff6137);
assert_eq!(orange, Color::rgb(255, 97, 55));

pub fn with_alpha(self, alpha: f32) -> Color

Creates a new color using the existing color and the given linear alpha value given as a float.

pub fn from_linear(value: Vec4) -> Color

Create a new Color from a linear RGB color.

pub fn adjust(&self, factor: f32) -> Color

Brighten or darken the color by multiplying it by a factor.

Values greater than 1 will lighten the color, values smaller than 1 will darken it.

This operation is gamma-correct.

pub fn to_linear(&self) -> Vec4

Convert this color to a linear RGB color.

pub fn lerp(&self, other: &Color, ratio: f32) -> Color

Blend with other in linear space

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<(), Error>

Formats the value using the given formatter.

impl From<[u8; 3]> for Color

fn from(value: [u8; 3]) -> Color

Converts to this type from the input type.

impl From<[u8; 4]> for Color

fn from(value: [u8; 4]) -> Color

Converts to this type from the input 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.
