Trait mz_ore::metrics::CounterVecExt

pub trait CounterVecExt {
    type CounterType: Atomic;

    // Required method
    fn get_delete_on_drop_counter<'a, L: PromLabelsExt<'a>>(
        &self,
        labels: L
    ) -> DeleteOnDropCounter<'a, Self::CounterType, L>;
}

Available on crate feature metrics only.

Extension trait for all gauge metrics vectors.

It adds a method to create a concrete metric from the vector that gets removed from the vector when the concrete metric is dropped.

Required Associated Types

type CounterType: Atomic

The type of value that the counter should count.

Required Methods

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

Returns a counter that deletes its labels from this metrics vector when dropped. See DeleteOnDropCounter for a detailed description.
