Trait mz_ore::metrics::PromLabelsExt

pub trait PromLabelsExt<'a> {
    // Required methods
    fn get_from_metric_vec<P: MetricVecBuilder>(
        &self,
        vec: &MetricVec<P>
    ) -> <P as MetricVecBuilder>::M;

}

Available on crate feature metrics only.

An extension trait for types that are valid (or convertible into) prometheus labels: slices/vectors of strings, and BTreeMaps.

Required Methods

fn get_from_metric_vec<P: MetricVecBuilder>( &self, vec: &MetricVec<P> ) -> <P as MetricVecBuilder>::M

Returns or creates a metric with the given metric label values. Panics if retrieving the metric returns an error.

fn remove_from_metric_vec<P: MetricVecBuilder>( &self, vec: &MetricVec<P> ) -> Result<(), Error>

Removes a metric with these labels from a metrics vector.

Object Safety

This trait is not object safe.
