Struct ExpMovingAverage 

Source 
pub struct ExpMovingAverage { /* private fields */ }
Expand description

Thread-safe exponential moving average used to track recent event rates.

Implementations§

Source§

impl ExpMovingAverage

Source

pub fn new(alpha: f64) -> Self

Creates a new moving average with smoothing factor alpha.

Lower values react more slowly to changes; higher values react faster.

Source

pub fn update(&self, count: usize)

Records count new events and updates the smoothed rate periodically.

Source

pub fn get_rate(&self) -> f64

Returns the current smoothed events-per-second rate.
