Struct Histogram 

pub struct Histogram(/* private fields */);

Stores an arbitrary number of data points, giving approximated information about its distribution. The current implementation uses an implementation of the DDSketch type but that might change in the future.

Implementations

impl Histogram

pub fn update(&self, value: f64)

Adds a sample to the histogram

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

Returns the estimated quantile value, which must be in the [0.0, 1.0] range, will panic otherwise. Returns None if the histogram is empty.

pub fn total(&self) -> f64

Returns the sum of all values stored in the histogram

pub fn count(&self) -> usize

Returns the number of values recorded.

pub fn is_empty(&self) -> bool

Returns true if the histogram contains 0 samples.

Trait Implementations

impl Clone for Histogram

fn clone(&self) -> Histogram

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.

impl Default for Histogram

fn default() -> Histogram

Returns the “default value” for a type.

impl From<Histogram> for MetricValue

fn from(value: Histogram) -> Self

Converts to this type from the input type.
