Struct Rgba8 

#[repr(C)]
pub struct Rgba8 {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

A color packed as four 8-bit channels, in memory order red, green, blue, alpha. Exactly four bytes, so a per-atom color column stays compact and uploads without conversion.

Fields

r: u8

Red channel, 0–255.

g: u8

Green channel, 0–255.

b: u8

Blue channel, 0–255.

a: u8

Alpha channel, 0–255; 255 is opaque.

Implementations

impl Rgba8

pub const WHITE: Self

Opaque white.

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

Builds a color from four channel values.

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

Builds an opaque color from three channel values.

pub fn to_f32(self) -> [f32; 4]

Converts to normalized floating-point channels in [0, 1].
