Struct AreaRng 

pub struct AreaRng {
    pub index: usize,
    pub label: Cow<'static, str>,
}

One bucket on the A-axis of an Accumulated — an index plus a label for rendering.

The canonical pycocotools detection layout is exposed as AreaRng::ALL / SMALL / MEDIUM / LARGE, matching the cocoeval Params.areaRngLbl order. Custom layouts (e.g., robotics-style finer buckets) are constructed with AreaRng::new for owned labels or AreaRng::from_static for &'static str labels.

The bounds that turn an annotation’s area into a bucket index live upstream, on the orchestrator that builds crate::accumulate::PerImageEval cells; the summarizer only consumes the resulting A-axis index.

Fields

index: usize

Position on the A-axis of Accumulated::precision / Accumulated::recall. Validated against the actual A-axis length at summarize time, not at construction; an out-of-range index produces EvalError::InvalidConfig.

label: Cow<'static, str>

Label rendered by Summary::pretty_lines.

Implementations

impl AreaRng

pub const ALL: Self

COCO all bucket — pycocotools’ [0, 1e10], A-axis index 0.

pub const SMALL: Self

COCO small bucket — pycocotools’ [0, 32^2], A-axis index 1.

pub const MEDIUM: Self

COCO medium bucket — pycocotools’ [32^2, 96^2], A-axis index 2.

pub const LARGE: Self

COCO large bucket — pycocotools’ [96^2, 1e10], A-axis index 3.

pub fn new(index: usize, label: impl Into<Cow<'static, str>>) -> Self

Construct from any owned- or borrowed-string label.

pub const fn from_static(index: usize, label: &'static str) -> Self

const-friendly constructor for compile-time labels.

Trait Implementations

impl Clone for AreaRng

fn clone(&self) -> AreaRng

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AreaRng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AreaRng

fn eq(&self, other: &AreaRng) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
