Enum MatchMetric 

#[repr(u32)]
pub enum MatchMetric {
    Iou = 0,
    Ios = 1,
}

Overlap metric used by the tiled-detection merge to decide whether two boxes belong to the same object.

The code is the one the C EF_MATCH_METRIC_* enumerators and the Python MatchMetric enum use.

Variants

Iou = 0

Intersection-over-Union (standard NMS metric).

Ios = 1

Intersection-over-Smaller (default): inter / min(area_a, area_b). A seam-split object has low IoU but high IoS, so IoS merges the fragment.

Implementations

impl MatchMetric

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 MatchMetric

pub fn value(self, a: &BoundingBox, b: &BoundingBox) -> f32

Metric value in [0, 1] for two boxes.
