Enum ColorRange 

#[non_exhaustive]
pub enum ColorRange {
    Full,
    Limited,
}

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.

Implementations

impl ColorRange

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

Short string label matching the EdgeFirst schema.

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.
