Struct SlidingWindowStats 

pub struct SlidingWindowStats { /* private fields */ }

Sliding window statistics

Maintains a fixed-size sliding window of recent values and computes statistics over that window.

Implementations

impl SlidingWindowStats

pub fn new(window_size: usize) -> AggregationResult<Self>

Create a new sliding window with the given size

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

Add a new value to the window

pub fn len(&self) -> usize

Get the current window size (may be less than max if not full)

pub fn is_empty(&self) -> bool

Check if the window is empty

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

Get the mean of values in the window

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

Get the min value in the window

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

Get the max value in the window

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

Get the median value in the window

pub fn percentile(&self, p: f64) -> AggregationResult<f64>

Get a percentile value (0-100)

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

Get standard deviation

pub fn reset(&mut self)

Reset the window
