Struct MetricsRegistry 

pub struct MetricsRegistry { /* private fields */ }

Registry of all remote-UDF metrics, owned by the registration handle.

Implementations

impl MetricsRegistry

pub fn new() -> Self

Create an empty registry.

pub fn function_metrics( &self, service_id: &str, function_name: &str, ) -> UdfMetrics

Get (or create) the metrics handle for a (service, function) pair.

pub fn service_metrics(&self, service_id: &str) -> ServiceMetrics

Get (or create) the per-service metrics handle.

pub fn to_prometheus(&self) -> String

Render every recorded metric in Prometheus text exposition format.

This is the export surface the observability stack scrapes; it is stable enough to snapshot-test. An empty registry renders an empty string.
