Struct ComponentMetrics 

pub struct ComponentMetrics { /* private fields */ }

Facade over a MetricsCollector for uniform component-operation emission. Construct via RuntimeObservability::component_metrics() or directly in tests.

Implementations

impl ComponentMetrics

pub fn new( collector: Arc<dyn MetricsCollector>, components_enabled: bool, ) -> Self

Builds a facade over collector; components_enabled is the snapshot of the [observability.metrics].components lever taken at construction time.

pub fn observe(&self, component: &str, operation: &str, failed: bool)

Observes one component operation. failed selects the closed-set outcome label (“failure”/“success”) and, when true, unconditionally forwards to the error family with the e:{component}:{operation} label — error-family emission is never lever-gated.
