Struct EvalGridMeta 

pub struct EvalGridMeta {
    pub n_categories: usize,
    pub n_area_ranges: usize,
    pub n_images: usize,
    pub category_id_to_idx: HashMap<CategoryId, usize>,
    pub image_id_to_idx: HashMap<ImageId, usize>,
}

Static metadata describing the (K, A, I) evaluation grid the streaming evaluator targets.

Built once at construction from the CocoDataset and the OwnedEvaluateParams — never mutated thereafter. Mirrors the axes the unchanged batch crate::evaluate_with orchestrator emits.

Fields

n_categories: usize

K axis size (number of categories, or 1 when use_cats=false).

n_area_ranges: usize

A axis size (number of area ranges).

n_images: usize

I axis size (number of images in the GT dataset).

category_id_to_idx: HashMap<CategoryId, usize>

Maps each GT CategoryId to its position on the K-axis. Empty when use_cats=false.

image_id_to_idx: HashMap<ImageId, usize>

Maps each GT ImageId to its position on the I-axis.
