Struct RiQuantileCalculator 

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

Quantile calculator for performance metrics.

This struct provides methods for calculating quantiles (percentiles) from a set of data points. It sorts the data and uses linear interpolation for non-integer indices.

Implementations§

Source§

impl RiQuantileCalculator

Source

pub fn new() -> Self

Creates a new quantile calculator.

§Returns

A new RiQuantileCalculator instance

Source
