Implementations§

§

impl Histogram

pub fn noop() -> Histogram

Creates a no-op Histogram which does nothing.

Suitable when a handle must be provided that does nothing i.e. a no-op recorder or a layer that disables specific metrics, and so on.

pub fn from_arc<F>(a: Arc<F>) -> Histogram
where F: HistogramFn + Send + Sync + 'static,

Creates a Histogram based on a shared handler.

pub fn record<T>(&self, value: T)
where T: IntoF64,

Records a value in the histogram.
