Struct ExponentialMovingAverage 

pub struct ExponentialMovingAverage<const FACTOR: usize> { /* private fields */ }

An exponential moving average calculator.

Based on the formula:

EMA_t = EMA_{t-1} + (Value_t - EMA_{t-1}) / min(t, FACTOR)

this object maintains a running average that emphasizes recent values more heavily and creates a smooth long-tailed averaging effect over time.

Implementations

impl<const FACTOR: usize> ExponentialMovingAverage<FACTOR>

pub fn update(&mut self, value: impl Into<f64>)

Updates the moving average with a new value.

pub fn get(&self) -> f64

Retrieves the current value of the moving average.

Trait Implementations

impl<const FACTOR: usize> Clone for ExponentialMovingAverage<FACTOR>

fn clone(&self) -> ExponentialMovingAverage<FACTOR>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const FACTOR: usize> Debug for ExponentialMovingAverage<FACTOR>

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

Formats the value using the given formatter.

impl<const FACTOR: usize> Default for ExponentialMovingAverage<FACTOR>

fn default() -> ExponentialMovingAverage<FACTOR>

Returns the “default value” for a type.

impl<const FACTOR: usize> PartialEq for ExponentialMovingAverage<FACTOR>

fn eq(&self, other: &ExponentialMovingAverage<FACTOR>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
