Struct smart_leds_trait::RGBA

#[repr(C)]
pub struct RGBA<ComponentType, AlphaComponentType = ComponentType> {
    pub r: ComponentType,
    pub g: ComponentType,
    pub b: ComponentType,
    pub a: AlphaComponentType,
}

The RGBA pixel

The component type can be u8 (aliased as RGBA8), u16 (aliased as RGBA16), or any other type (but simple copyable types are recommended.)

You can specify a different type for alpha, but it’s only for special cases (e.g. if you use a newtype like RGBA<LinearLight<u16>, u16>).

Fields

r: ComponentType

Red

g: ComponentType

Green

b: ComponentType

Blue

a: AlphaComponentType
