Struct PerImageEvalStore 

pub struct PerImageEvalStore { /* private fields */ }

Sparse (k, a, i) -> PerImageEval store backing the streaming evaluator.

Cells absent from the store represent the same “no detections, no non-ignore GTs” condition as None entries in the batch crate::EvalGrid::eval_imgs. Self::flatten re-densifies the store into the dense Vec<Option<PerImageEval>> shape crate::accumulate consumes.

Implementations

impl PerImageEvalStore

pub fn new() -> Self

Empty store.

pub fn len(&self) -> usize

Number of populated cells.

pub fn is_empty(&self) -> bool

true if no cells have been inserted.

pub fn insert(&mut self, k: usize, a: usize, i: usize, cell: PerImageEval)

Insert (or overwrite) the cell at (k, a, i).

pub fn flatten(&self, meta: &EvalGridMeta) -> Vec<Option<Box<PerImageEval>>>

Densify into the [k * A * I + a * I + i]-laid-out Vec<Option<Box<PerImageEval>>> that crate::accumulate consumes. Cloning is intentional — accumulate borrows the slice and the store must remain valid for further updates after a snapshot. The cells are heap-boxed so the dense slot Vec only pays for a pointer per slot at zero-init time (see crate::EvalGrid::eval_imgs).

Trait Implementations

impl Clone for PerImageEvalStore

fn clone(&self) -> PerImageEvalStore

impl Default for PerImageEvalStore

fn default() -> PerImageEvalStore

Returns the “default value” for a type.
