Required Associated Types

type Inner

The inner type for the ObserveWhen.

The observe can be delegated to a different type then Self, however the latter is more common.

Required Methods

fn observe<F>( &self, metric: impl Deref<Target = InputMetric>, operation: F, ) -> ObserveWhen<'_, Self::Inner, F>

where F: Fn(Instant) -> MetricValue + Send + Sync + 'static, Self: Sized,

Provide a source for a metric’s values.
