Struct Histogram 

pub struct Histogram {
    pub min: f64,
    pub max: f64,
    pub counts: Vec<u64>,
}

Equal-width histogram over [min, max]. counts.len() is the bin count.

Fields

min: f64

Lower edge of the first bin, in raw sample units.

max: f64

Upper edge of the final bin, in raw sample units.

counts: Vec<u64>

Counts in ascending equal-width bins. Empty or all-zero counts give Self::min when querying a quantile; their sum may exceed u64::MAX.

Implementations

impl Histogram

pub fn quantile(&self, p: f64) -> f64

Value at percentile p (0..=100) via linear interpolation on the cumulative count. Robust to the overview-smoothing approximation of a sampled overview. Empty / degenerate → min. Counts may sum beyond u64::MAX; accumulation uses u128 and only the interpolation converts to f64. The 100th percentile is the upper edge of the last nonempty bin, excluding any trailing zero-count bins.

Trait Implementations

impl Clone for Histogram

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Histogram

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

Formats the value using the given formatter.
