Struct Histogram

pub struct Histogram { /* private fields */ }

Histogram with exponential bucket boundaries.

Bucket boundaries are in seconds. Default: [0.001, 0.01, 0.1, 1, 10].

Implementations

impl Histogram

pub fn new(name: impl Into<String>, buckets: &[f64]) -> Self

Build a histogram with finite bucket boundaries, sorted ascending and deduplicated. Non-finite values are ignored; the implicit +Inf bucket is always appended by Self::bucket_counts.

pub fn observe(&self, d: Duration)

pub fn count(&self) -> u64

pub fn sum_seconds(&self) -> f64

pub fn bucket_counts(&self) -> Vec<(f64, u64)>

pub fn name(&self) -> &str

Trait Implementations

impl Debug for Histogram

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

Formats the value using the given formatter.
