Fields

__private_field: ()

Methods from Deref<Target = Histogram>

pub fn observe(&self, v: f64)[src]

Add a single observation to the Histogram.

pub fn start_timer(&self) -> HistogramTimer[src]

Return a HistogramTimer to track a duration.

pub fn start_coarse_timer(&self) -> HistogramTimer[src]

Return a HistogramTimer 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, 
[src]

Observe execution time of a closure, in second.

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

Observe execution time of a closure, in second.

pub fn local(&self) -> LocalHistogram[src]

Return a LocalHistogram for single thread usage.

pub fn get_sample_sum(&self) -> f64[src]

Return accumulated sum of all samples.

pub fn get_sample_count(&self) -> u64[src]

Return count of all samples.
