Type Alias DeleteOnDropGauge 

pub type DeleteOnDropGauge<P, L> = DeleteOnDropMetric<GenericGaugeVec<P>, L>;

Available on crate feature metrics only.

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

Aliased Type

pub struct DeleteOnDropGauge<P, L> {
    inner: <MetricVec<GaugeVecBuilder<P>> as MetricVec_>::M,
    cleanup: Arc<DeleteOnDropCleanup<MetricVec<GaugeVecBuilder<P>>, L>>,
}

Fields

inner: <MetricVec<GaugeVecBuilder<P>> as MetricVec_>::M

cleanup: Arc<DeleteOnDropCleanup<MetricVec<GaugeVecBuilder<P>>, L>>

Shared cleanup handle. The label is removed from vec only when the last clone drops. Held purely for its Drop side effect — never read directly.
