Struct prometheus::local::LocalHistogram

pub struct LocalHistogram { /* fields omitted */ }

An unsync Histogram.

Implementations

impl LocalHistogram

pub fn observe(&self, v: f64)

Add a single observation to the Histogram.

pub fn start_timer(&self) -> LocalHistogramTimer

Return a LocalHistogramTimer to track a duration.

pub fn start_coarse_timer(&self) -> LocalHistogramTimer

Return a LocalHistogramTimer to track a duration. It is faster but less precise.

pub fn observe_closure_duration<F, T>(&self, f: F) -> T where
    F: FnOnce() -> T, 

Observe execution time of a closure, in second.

pub fn observe_closure_duration_coarse<F, T>(&self, f: F) -> T where
    F: FnOnce() -> T, 

Observe execution time of a closure, in second.

pub fn clear(&self)

Clear the local metric.

pub fn flush(&self)

Flush the local metrics to the Histogram metric.

pub fn get_sample_sum(&self) -> f64

Return accumulated sum of local samples.

pub fn get_sample_count(&self) -> u64

Return count of local samples.
