Struct MetricsSnapshot 

pub struct MetricsSnapshot {
    pub counts: Vec<MetricCount>,
    pub histograms: Vec<MetricHistogram>,
}

Point-in-time snapshot of every metric a MetricsTelemetry has accumulated. Implements Serialize so callers can hand it straight to a JSON / Prometheus exposition layer.

Fields

counts: Vec<MetricCount>

histograms: Vec<MetricHistogram>

Implementations

impl MetricsSnapshot

pub fn to_prometheus(&self) -> String

Render every metric in Prometheus exposition-format text. Callers can serve this directly from a /metrics HTTP endpoint without any extra exporter library.

Format reference: https://prometheus.io/docs/instrumenting/exposition_formats/
