Struct mz_ore::metrics::DeleteOnDropMetric

pub struct DeleteOnDropMetric<'a, V, L>
where
    V: MetricVec_,
    L: PromLabelsExt<'a>,
{
    inner: V::M,
    labels: L,
    vec: V,
    _phantom: &'a PhantomData<()>,
}

Available on crate feature metrics only.

A Metric 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.

Fields

inner: V::M

labels: L
