Enum YuvMatrix 

#[non_exhaustive]
#[repr(u8)]
pub enum YuvMatrix {
    Identity = 0,
    Bt601 = 1,
    Bt709 = 2,
    Bt2020 = 3,
}

YCbCr matrix coefficients for luma/chroma conversion.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Identity = 0

Identity / not applicable (RGB, Gray, Oklab, etc.).

Bt601 = 1

BT.601: Y = 0.299R + 0.587G + 0.114B (JPEG, WebP, SD video).

Bt709 = 2

BT.709: Y = 0.2126R + 0.7152G + 0.0722B (AVIF, HEIC, HD video).

Bt2020 = 3

BT.2020: Y = 0.2627R + 0.6780G + 0.0593B (4K/8K HDR).
