Struct RunningAgg 

Source 
pub struct RunningAgg {
    pub total_sum: f64,
    pub total_count: u64,
    pub window: VecDeque<f64>,
    pub window_size: usize,
}
Expand description

Running aggregate per relevancy metric. Holds both the all-time running mean and a bounded sliding window so progress views can show recent trend alongside the cumulative average.

Fields§

§total_sum: f64

Sum of every score ever recorded (for all-time mean).

§total_count: u64

Count of scores recorded (for all-time mean).

§window: VecDeque<f64>

Recent scores, newest at the back. Capped at window_size.

§window_size: usize

Upper bound on window length.
