Enum ColorSpace 

#[non_exhaustive]
#[repr(u32)]
pub enum ColorSpace {
    Bt709 = 1,
    Bt2020 = 2,
    Srgb = 3,
    Smpte170m = 4,
}

Color primaries (color_space in the EdgeFirst schema).

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

Bt2020 = 2

Srgb = 3

Smpte170m = 4

Implementations

impl ColorSpace

pub const fn code(self) -> u32

The shared code for this variant. Identical on every surface.

const, deliberately: a downstream binding that cannot write Variant = OtherEnum::Variant.code() in a #[pyclass] discriminant position (PyO3 requires a literal there) can still pin that literal to this value with a const _: () = assert!(...) – a build-time check instead of a hand-synced comment. See PyTensorMemory/PyPixelFormat in crates/python-common/src/tensor.rs for the consumer.

pub fn from_code(code: u32) -> Option<Self>

Reject an unknown code rather than guessing at one.

pub fn as_str(self) -> &'static str

The wire string form – stable, unlike Debug.

pub fn from_str_code(s: &str) -> Option<Self>

Reject an unknown string rather than guessing at one.

pub fn all() -> &'static [Self]

Every variant, for exhaustive cross-surface tests.

impl ColorSpace

pub fn from_v4l2(v: u32) -> Option<Self>

Map a raw V4L2 colorspace field to a ColorSpace.

Returns None for V4L2_COLORSPACE_DEFAULT (0) and any unrecognised value.
