Enum ColorPrimaries 

#[non_exhaustive]
#[repr(u8)]
pub enum ColorPrimaries {
    Bt709 = 1,
    Bt2020 = 9,
    DisplayP3 = 12,
    Unknown = 255,
}

Color primaries (CIE xy chromaticities of R, G, B).

Discriminant values match CICP ColorPrimaries codes (ITU-T H.273).

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 = 1

BT.709 / sRGB (CICP 1).

Bt2020 = 9

BT.2020 / BT.2100 (CICP 9). Wide gamut for HDR.

DisplayP3 = 12

Display P3 (CICP 12). Apple ecosystem, wide gamut SDR.

Unknown = 255

Primaries not known.

Implementations

impl ColorPrimaries

pub const fn from_cicp(code: u8) -> Option<ColorPrimaries>

Map a CICP color_primaries code to a ColorPrimaries.

pub const fn to_cicp(self) -> Option<u8>

Convert to the CICP color_primaries code.

pub const fn contains(self, other: ColorPrimaries) -> bool

Whether self fully contains the gamut of other.

Gamut hierarchy: BT.2020 > Display P3 > BT.709.

Trait Implementations

impl Clone for ColorPrimaries

fn clone(&self) -> ColorPrimaries

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ColorPrimariesExt for ColorPrimaries

fn to_xyz_matrix(&self) -> Option<&'static GamutMatrix>

Linear RGB → CIE XYZ (D65 white point).

fn from_xyz_matrix(&self) -> Option<&'static GamutMatrix>

CIE XYZ (D65 white point) → linear RGB.

impl Debug for ColorPrimaries

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ColorPrimaries

fn default() -> ColorPrimaries

Returns the “default value” for a type.

impl Display for ColorPrimaries

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for ColorPrimaries

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColorPrimaries

fn eq(&self, other: &ColorPrimaries) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
