Struct TDigest 

pub struct TDigest { /* private fields */ }

T-Digest state. Append samples with Self::add, then query quantiles with Self::quantile. Two digests merge losslessly via Self::merge — the parallel-aggregate path.

Implementations

impl TDigest

pub fn new() -> TDigest

pub fn with_compression(compression: f64) -> TDigest

pub fn is_empty(&self) -> bool

pub fn count(&self) -> f64

pub fn min(&self) -> f64

pub fn max(&self) -> f64

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

Append a single sample with implicit weight 1.

pub fn add_weighted(&mut self, value: f64, weight: f64)

Append a single sample with explicit weight.

pub fn merge(&mut self, other: &TDigest)

Merge another digest into this one. Both digests retain the same compression target; min/max combine; the merged buffer is flushed to keep the centroid list canonical.

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

Estimate the q-quantile, q ∈ [0.0, 1.0].

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for TDigest

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

Formats the value using the given formatter.

impl Default for TDigest

fn default() -> TDigest

Returns the “default value” for a type.
