Trait dipstick::Observe

    type Inner;

    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;

Schedule a recurring task

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.
