Enum ColorMode 

#[repr(u32)]
pub enum ColorMode {
    Class = 0,
    Instance = 1,
    Track = 2,
}

Controls how the color palette index is chosen for each detected object.

Variants

Class = 0

Color is chosen by object class label (det.label). Default.

Preserves backward compatibility and is correct for semantic segmentation where colors carry class meaning.

Instance = 1

Color is chosen by instance order (loop index, zero-based).

Each detected object gets a unique color regardless of class, useful for instance segmentation.

Track = 2

Color is chosen by track ID (future use; currently behaves like Instance).

Implementations

impl ColorMode

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 ColorMode

pub fn index(self, idx: usize, label: usize) -> usize

Return the palette index for a detection given its loop index and label.
