Struct stretto::Histogram

source · [−]

pub struct Histogram { /* private fields */ }

Expand description

Histogram stores the information needed to represent the sizes of the keys and values as a histogram.

Histogram promises thread-safe.

Implementations

source

impl Histogram

source

pub fn new(bounds: Vec<f64>) -> Self

Returns a new instance of HistogramData with properly initialized fields.

source

pub fn update(&self, val: i64)

Returns HistogramData base on the min exponent and max exponent. The bounds are powers of two of the form [2^min_exponent, …, 2^max_exponent]. update changes the Min and Max fields if value is less than or greater than the current values.

source

pub fn mean(&self) -> f64

mean returns the mean value for the histogram.

source

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

percentile returns the percentile value for the histogram. value of p should be between [0.0-1.0]

source

pub fn clear(&self)

clear reset the histogram. Helpful in situations where we need to reset the metrics
