Struct ExponentialMovingAverage 

pub struct ExponentialMovingAverage { /* private fields */ }

Exponential moving average with configurable smoothing factor α.

EMA_n = α * value + (1 - α) * EMA_{n-1}. Smaller α → smoother but slower to respond.

Implementations

impl ExponentialMovingAverage

pub fn new(alpha: f64) -> Self

Create a new EMA. alpha must be in (0, 1].

A good default for frame times is α = 0.1 (90% weight on history).

pub fn with_samples(n: f64) -> Self

Create an EMA tuned to smooth over approximately n samples.

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

Update with a new observation.

pub fn get(&self) -> f64

Get the current EMA value.

pub fn sample_count(&self) -> u64

Number of samples seen.

pub fn reset(&mut self)

Reset the EMA to uninitialized state.

pub fn alpha(&self) -> f64

Current smoothing factor.
