Trait MeasureLatency

pub trait MeasureLatency: Sized {
    // Required methods
    fn measure_latency(&self) -> ActiveMeasurementGuard<'_, Self>;
    fn finish_measurement(&self, milliseconds: f64);
}

An extension trait for metrics that can be used to measure latencies.

Required Methods

fn measure_latency(&self) -> ActiveMeasurementGuard<'_, Self>

Starts measuring the latency, finishing when the returned ActiveMeasurementGuard is dropped.

fn finish_measurement(&self, milliseconds: f64)

Updates the metric with measured latency in milliseconds.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
