Enum ColorRange 

#[non_exhaustive]
#[repr(u32)]
pub enum ColorRange {
    Full = 1,
    Limited = 2,
}

Quantization range (color_range 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.

Full = 1

Limited = 2

Implementations

impl ColorRange

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 ColorRange

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

Map a raw V4L2 quantization field to a ColorRange.

Returns None for V4L2_QUANTIZATION_DEFAULT (0) and any unrecognised value.

impl ColorRange

pub fn scaling(self) -> RangeScaling

The luma/chroma quantization swings for this range — the canonical 0/255/255 (full) or 16/219/224 (limited) studio-swing constants shared by every YUV↔RGB conversion path.
