Trait Implementations

impl<T: Clone> Clone for NoopHandle<T>

fn clone(&self) -> NoopHandle<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> CounterHandle<T> for NoopHandle<T> where
    T: Into<MeasurementValue>, 

fn add(&self, value: T)

Add works by calling the underlying record_one method available because this trait also implements InstrumentHandle.

impl<T: Debug> Debug for NoopHandle<T>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T> GaugeHandle<T> for NoopHandle<T> where
    T: Into<MeasurementValue>, 

fn set(&self, value: T)

Set works by calling the underlying record_one method available because this trait also implements InstrumentHandle.

impl<T> Instrument<NoopLabelSet> for NoopHandle<T>

fn record_one(&self, _value: MeasurementValue, _label_set: &NoopLabelSet)

Allows the SDK to observe a single metric event for a given set of labels.

impl<T> InstrumentHandle for NoopHandle<T>

fn record_one(&self, _value: MeasurementValue)

Ignores all measurement values.

impl<T> MeasureHandle<T> for NoopHandle<T> where
    T: Into<MeasurementValue>, 

fn record(&self, value: T)

Record works by calling the underlying record_one method available because this trait also implements InstrumentHandle.
