Struct linera_base::prometheus_util::ActiveMeasurementGuard

source · 
pub struct ActiveMeasurementGuard<'metric, Metric>
where
    Metric: MeasureLatency,
{ /* private fields */ }
Expand description

A guard for an active latency measurement.

Finishes the measurement when dropped, and then updates the Metric.
