Struct StepSummary 

pub struct StepSummary {
    pub objective_sum: f64,
    pub frame_count: usize,
    pub weight_sum: f64,
    pub per_frame_objective: BTreeMap<usize, f64>,
}

Universal, algorithm-neutral information produced by one batch step.

Fields

objective_sum: f64

Sum of per-frame objectives multiplied by frame weights.

frame_count: usize

Number of frames visited, including zero-weight frames.

weight_sum: f64

Sum of non-negative reconstruction weights for visited frames.

per_frame_objective: BTreeMap<usize, f64>

Unweighted objective for each visited acquisition-frame index.

Implementations

impl StepSummary

pub fn push_frame(&mut self, frame: usize, objective: f64, weight: f64)

Accumulates one frame’s objective and reconstruction weight.

pub fn mean_objective(&self) -> Option<f64>

Returns the weight-normalized objective, or None when total weight is zero.

pub fn merge(&mut self, other: Self)

Deterministically combines counts, sums, and per-frame values from another batch.
