pub fn i64_observable_up_down_counter( &self, name: impl Into<Cow<'static, str>> ) -> AsyncInstrumentBuilder<'_, ObservableUpDownCounter<i64>, i64>

creates an instrument builder for recording changes of a value via callback.

pub fn f64_observable_up_down_counter( &self, name: impl Into<Cow<'static, str>> ) -> AsyncInstrumentBuilder<'_, ObservableUpDownCounter<f64>, f64>

creates an instrument builder for recording changes of a value via callback.

pub fn u64_observable_gauge( &self, name: impl Into<Cow<'static, str>> ) -> AsyncInstrumentBuilder<'_, ObservableGauge<u64>, u64>

creates an instrument builder for recording the current value via callback.

pub fn i64_observable_gauge( &self, name: impl Into<Cow<'static, str>> ) -> AsyncInstrumentBuilder<'_, ObservableGauge<i64>, i64>

creates an instrument builder for recording the current value via callback.

pub fn f64_observable_gauge( &self, name: impl Into<Cow<'static, str>> ) -> AsyncInstrumentBuilder<'_, ObservableGauge<f64>, f64>

creates an instrument builder for recording the current value via callback.

pub fn f64_histogram( &self, name: impl Into<Cow<'static, str>> ) -> InstrumentBuilder<'_, Histogram<f64>>

creates an instrument builder for recording a distribution of values.

pub fn u64_histogram( &self, name: impl Into<Cow<'static, str>> ) -> InstrumentBuilder<'_, Histogram<u64>>

creates an instrument builder for recording a distribution of values.

pub fn i64_histogram( &self, name: impl Into<Cow<'static, str>> ) -> InstrumentBuilder<'_, Histogram<i64>>

pub fn register_callback<F>( &self, instruments: &[Arc<dyn Any>], callback: F ) -> Result<Box<dyn CallbackRegistration>>where F: Fn(&dyn Observer) + Send + Sync + 'static,

Registers a callback to be called during the collection of a measurement cycle.

The instruments passed as arguments to be registered are the only instruments that may observe values.

If no instruments are passed, the callback will not be registered.
