Enum ChannelLayout 

pub enum ChannelLayout {
    Gray,
    GrayAlpha,
    Rgb,
    Rgba,
}

The channel layout of a pixel, independent of sample type.

Exhaustive for the same reason as SampleKind: kernels dispatch on it.

Variants

Gray

Single luminance channel.

GrayAlpha

Luminance plus unassociated alpha.

Rgb

Red, green, blue.

Rgba

Red, green, blue, plus unassociated alpha.
