Trait SMA

pub trait SMA<T> {
    // Required methods
    fn push(&mut self, sample: T);
    fn average(&self) -> Option<T>;
    fn window_size(&self) -> usize;
    fn len(&self) -> usize;
    fn is_empty(&self) -> bool;

    // Provided method
    fn is_window_full(&self) -> bool { ... }
}

Simple Moving Average trait.

The second-most useful filter type, bested only by coffee filters.

Required Methods

fn push(&mut self, sample: T)

Pushes a sample.

fn average(&self) -> Option<T>

Calculates the moving average value. Returns None if no samples were added.

fn window_size(&self) -> usize

Returns the window size.

fn len(&self) -> usize

Returns the number of elements in the window. This value is always between 0 and window_size().

fn is_empty(&self) -> bool

Indicates whether there are no samples.

Provided Methods

fn is_window_full(&self) -> bool

Indicates whether the window is fully occupied with samples.
