Struct tikv::storage::mvcc::metrics::MVCC_VERSIONS_HISTOGRAM [−][src]
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]
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, [src]
F: FnOnce() -> T,
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.
