pub struct ObservabilityRegistry {
    pub tracer: Arc<Tracer>,
    pub metrics: Arc<Mutex<Vec<MetricPoint>>>,
}

Central registry that combines a Tracer with an in-process metrics store and Prometheus export.

Fields

tracer: Arc<Tracer>

The tracer used to create spans.

metrics: Arc<Mutex<Vec<MetricPoint>>>

Accumulated metric observations.

Implementations

impl ObservabilityRegistry

pub fn new(tracer: Arc<Tracer>) -> Self

Creates a new registry wrapping the given Tracer.

pub fn record_metric( &self, name: &str, value: f64, labels: HashMap<String, String>, )

Records a metric observation.

pub fn to_prometheus(&self) -> String

Serializes all recorded metrics in the Prometheus exposition format.

Each metric is emitted as:
