Struct mz_ore::metrics::DeleteOnDropWrapper

pub struct DeleteOnDropWrapper<M> { /* private fields */ }

Available on crate feature metrics only.

A wrapper for metrics to require delete on drop semantics

The wrapper behaves like regular metrics but only provides functions to create delete-on-drop variants. This way, no metrics of this type can be leaked.

In situations where the delete-on-drop behavior is not desired or in legacy code, use the raw variants of the metrics, as defined in self::raw.

Trait Implementations

impl<M: Clone> Clone for DeleteOnDropWrapper<M>

fn clone(&self) -> DeleteOnDropWrapper<M>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M: Collector> Collector for DeleteOnDropWrapper<M>

fn desc(&self) -> Vec<&Desc>

Return descriptors for metrics.

fn collect(&self) -> Vec<MetricFamily>

Collect metrics.

impl<M: CounterVecExt> CounterVecExt for DeleteOnDropWrapper<M>

type CounterType = <M as CounterVecExt>::CounterType

The type of value that the counter should count.

fn get_delete_on_drop_counter<'a, L: PromLabelsExt<'a>>( &self, labels: L ) -> DeleteOnDropCounter<'a, Self::CounterType, L>
