pub struct LocalHistogram { /* fields omitted */ }

[−] Expand description

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.
