Struct ColorRgba8 

#[repr(C)]
pub struct ColorRgba8 {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

A packed 8-bit RGBA color, laid out in RGBA byte order. 一个打包的 8 位 RGBA 颜色，按 RGBA 字节顺序排列。

This is the storage format for textures and framebuffers. 这是纹理和帧缓冲的存储格式。

Fields

r: u8

g: u8

b: u8

a: u8
