Enum ColorPrimaries 

#[non_exhaustive]
pub enum ColorPrimaries {
    Bt709,
    AdobeRgb,
    DciP3,
    Bt2020,
}

The container colorimetry a producer says its layer is in.

The friendly producer-side description, distinct from Colorspace, which is what the driver advertises on a connector. The scene picks the connector enum that best matches the widest-gamut layer at commit time.

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.

Bt709

BT.709 / sRGB. The SDR default.

AdobeRgb

Adobe RGB (1998).

DciP3

DCI-P3 D65, display-referred consumer P3.

Bt2020

BT.2020 / Rec.2100. HDR and wide-gamut SDR.

Implementations

impl ColorPrimaries

pub const fn is_wider_than(self, other: Self) -> bool

Whether self is a wider gamut than other.

Variants are declared widest last, so the derived Ord ranks gamut directly.

Deliberate: a separate rank function and a variant order that disagreed would be a silent mis-ranking, and there is nothing to notice it. Adding a variant in the wrong place breaks a test here rather than a picture on a display.

pub const fn colorimetry(self) -> ColorimetryInfo

Canonical CIE 1931 chromaticities, ready to seed mastering-display primaries.

All four are D65-white.

pub const fn colorspace(self) -> Colorspace

The connector enum that best carries this.
