Struct PlateauDetector 

pub struct PlateauDetector {
    pub window_size: usize,
    pub variance_threshold: f64,
    /* private fields */
}

Plateau detector: detects when a metric has plateaued.

A plateau is detected when the variance of the most recent values within a sliding window falls below a configurable threshold.

Fields

window_size: usize

Size of the sliding window.

variance_threshold: f64

Variance threshold below which a plateau is declared.

Implementations

impl PlateauDetector

pub fn new(window_size: usize, variance_threshold: f64) -> Self

Create a new plateau detector.

pub fn push(&mut self, value: f64)

Push a new metric value.

pub fn is_plateau(&self) -> bool

Whether the metric has plateaued (window full and variance below threshold).

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

Compute the variance of the values in the current window.

Returns None if there are fewer values than the window size.

pub fn values_in_window(&self) -> &[f64]

The values currently in the sliding window.

Trait Implementations

impl Clone for PlateauDetector

fn clone(&self) -> PlateauDetector

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlateauDetector

fn fmt(&self, f: &mut Formatter<'_>) -> Result
