Trait PromLabelsExt 

pub trait PromLabelsExt {
    // Required methods
    fn get_from_metric_vec<V: MetricVec_>(&self, vec: &V) -> V::M;
    fn remove_from_metric_vec<V: MetricVec_>(
        &self,
        vec: &V,
    ) -> Result<(), Error>;
}

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<V: MetricVec_>(&self, vec: &V) -> V::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<V: MetricVec_>(&self, vec: &V) -> Result<(), Error>

Removes a metric with these labels from a metrics vector.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
