SDK implemented trait for creating instruments

Required Methods

fn register_callback( &self, callback: Box<dyn Fn(&Context) + Send + Sync> ) -> Result<()>

Captures the function that will be called during data collection.

It is only valid to call observe within the scope of the passed function.

Provided Methods

fn u64_counter( &self, _name: String, _description: Option<String>, _unit: Option<Unit> ) -> Result<Counter<u64>>

creates an instrument for recording increasing values.

fn f64_counter( &self, _name: String, _description: Option<String>, _unit: Option<Unit> ) -> Result<Counter<f64>>

creates an instrument for recording increasing values.

fn u64_observable_counter( &self, _name: String, _description: Option<String>, _unit: Option<Unit> ) -> Result<ObservableCounter<u64>>

creates an instrument for recording increasing values via callback.

fn f64_observable_counter( &self, _name: String, _description: Option<String>, _unit: Option<Unit> ) -> Result<ObservableCounter<f64>>
