Struct StalenessWindow 

pub struct StalenessWindow { /* private fields */ }

A staleness-weighted window of recent scalar observations (e.g. per-step loss under the current config). push advances the clock; weighted_mean reports the freshness-weighted average; observations past k2 are evicted.

Implementations

impl StalenessWindow

pub fn new(schedule: StalenessSchedule, cap: usize) -> Self

New window with the given schedule and a hard capacity cap.

pub fn push(&mut self, value: f32)

Record an observation under the current config; advances the clock and evicts samples that are too stale (age > k2) or over capacity.

pub fn clear_samples(&mut self)

Reset the recorded observations but keep the clock running — used after a config switch so the new config is scored on its own fresh samples.

pub fn weighted_mean(&self) -> Option<f32>

Staleness-weighted mean of the window, or None if empty / all-stale.

pub fn clock(&self) -> u64

Current clock (number of observations ever pushed).

pub fn len(&self) -> usize

Number of live (non-evicted) observations.

pub fn is_empty(&self) -> bool

Whether the window holds no live observations.
