Required Methods

fn basename(&self) -> String

fn parent_hierarchy(&self) -> Vec<String>

Provided Methods

fn hierarchy(&self) -> String

Retrieve the complete hierarchy and basename for this registry. Currently, the hierarchy for drt is an empty string, so we must account for the leading underscore. The existing code remains unchanged to accommodate any future scenarios where drt’s prefix might be assigned a value.

fn create_counter( &self, name: &str, description: &str, labels: &[(&str, &str)], ) -> Result<Counter>

Create a Counter metric

fn create_countervec( &self, name: &str, description: &str, const_labels: &[&str], const_label_values: &[(&str, &str)], ) -> Result<CounterVec>

Create a CounterVec metric with label names (for dynamic labels)

fn create_gauge( &self, name: &str, description: &str, labels: &[(&str, &str)], ) -> Result<Gauge>

Create a Gauge metric

fn create_histogram( &self, name: &str, description: &str, labels: &[(&str, &str)], buckets: Option<Vec<f64>>, ) -> Result<Histogram>

Create a Histogram metric with custom buckets

fn create_intcounter( &self, name: &str, description: &str, labels: &[(&str, &str)], ) -> Result<IntCounter>

Create an IntCounter metric

fn create_intcountervec( &self, name: &str, description: &str, const_labels: &[&str], const_label_values: &[(&str, &str)], ) -> Result<IntCounterVec>

Create an IntCounterVec metric with label names (for dynamic labels)

fn create_intgauge( &self, name: &str, description: &str, labels: &[(&str, &str)], ) -> Result<IntGauge>

Create an IntGauge metric

fn create_intgaugevec( &self, name: &str, description: &str, const_labels: &[&str], const_label_values: &[(&str, &str)], ) -> Result<IntGaugeVec>

Create an IntGaugeVec metric with label names (for dynamic labels)

fn prometheus_metrics_fmt(&self) -> Result<String>

Get metrics in Prometheus text format
