SDK implemented trait for creating instruments

Required Methods

fn register_callback( &self, instruments: &[Arc<dyn Any, Global>], callbacks: Box<dyn Fn(&dyn Observer) + Sync + Send, Global> ) -> Result<Box<dyn CallbackRegistration, Global>, MetricsError>

Captures the function that will be called during data collection.

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