Struct ComponentMetrics 

pub struct ComponentMetrics { /* private fields */ }

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

Cheap to clone: the collector sits behind an Arc, so one facade can be shared across objects built from the same connection (e.g. a repository and its payload store).

Implementations

impl ComponentMetrics

pub fn new( collector: Arc<dyn MetricsCollector>, component: impl Into<Arc<str>>, enabled: bool, ) -> Self

Builds a facade over collector with the component identity fixed to component; enabled is the effective per-component switch (ComponentMetricsLevers::enabled_for) snapshot taken at construction time.

pub fn component(&self) -> &str

Returns the component identity fixed at construction.

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

Observes one component operation for the fixed identity. 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.

Trait Implementations

impl Clone for ComponentMetrics

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
