Struct duku::Rgb

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

Color bytes in RGB with alpha.

Makes it easier to handle/convert colors.

Examples

let red = Rgb::red(50);

Fields

r: u8

the red component

g: u8

the green component

b: u8

the blue component

a: u8

the alpha component

Implementations

impl Rgb

pub const fn new(r: u8, g: u8, b: u8) -> Self

Create color

pub const fn gray(v: u8) -> Self

Create color with the same value for all components

pub const fn red(v: u8) -> Self

Create color with setting only the red component

pub const fn green(v: u8) -> Self

Create color with setting only the green component

pub const fn blue(v: u8) -> Self

Create color with setting only the blue component

pub const fn clear() -> Self

Create transparent color

pub const fn alpha(self, a: u8) -> Self

Create color, modifying the color's alpha

Examples

let color = Rgb::blue(128).alpha(50);
