Struct mz_ore::metrics::DeleteOnDropHistogram

pub struct DeleteOnDropHistogram<'a, L>
where
    L: PromLabelsExt<'a>,
{ /* private fields */ }

Available on crate feature metrics only.

A GenericCounter wrapper that deletes its labels from the vec when it is dropped

It adds a method to create a concrete metric from the vector that gets removed from the vector when the concrete metric is dropped.

NOTE: This type implements Borrow, which imposes some constraints on implementers. To ensure these constraints, do not implement any of the Eq, Ord, or Hash traits on this. type.

Methods from Deref<Target = Histogram>

pub fn observe(&self, v: f64)

Add a single observation to the Histogram.

pub fn start_timer(&self) -> HistogramTimer

Return a HistogramTimer to track a duration.

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 local(&self) -> LocalHistogram

Return a LocalHistogram for single thread usage.

pub fn get_sample_sum(&self) -> f64

Return accumulated sum of all samples.

pub fn get_sample_count(&self) -> u64

Return count of all samples.
