Type Alias metrics::Histogram

pub type Histogram<T> = DetailedHistogram<T, T>;

A helper type alias for Histogram that doesn’t store details. The structure can be used in production without much memory penalty.

Aliased Type

struct Histogram<T> {
    buckets: Vec<Bucket<T>>,
    values: Option<Vec<T>>,
}

Fields

buckets: Vec<Bucket<T>>

values: Option<Vec<T>>

Implementations

impl<T: NumberType, D: Details<T>> DetailedHistogram<T, D>

fn new_internal(ranges: &[Range<T>], details: bool) -> Result<Self>

pub fn new(ranges: &[Range<T>]) -> Result<Self>

Creates an histogram with given ranges of buckets.

pub fn add(&mut self, value: D) -> Result<()>
