Struct RateWindow 

pub struct RateWindow { /* private fields */ }

Sliding-bucket rate counter. Tracks per-second event counts in a fixed ring of length window_secs. Provides observe_and_score which:

1. Increments the current second’s bucket.
2. Computes the mean + std-dev across the ring.
3. Returns z-score = (current_rate - mean) / std-dev when the window is fully populated AND std-dev > 0.

Implementations

impl RateWindow

pub fn new(window_secs: u64) -> Self

pub fn observe_and_score(&mut self, now: Instant) -> Option<SpikeScore>

Bump the current bucket by one event and return a SpikeScore when the window has accumulated enough data to be meaningful (full window AND non-zero std-dev).
