}

This is supported on crate feature metrics only.

The interface an SDK must implement to supply a Meter implementation.

Required methods

fn record_batch_with_context(
    &self,
    cx: &Context,
    attributes: &[KeyValue],
    measurements: Vec<Measurement>
)

Atomically record a batch of measurements.

fn new_sync_instrument(
    &self,
    descriptor: Descriptor
) -> Result<Arc<dyn SyncInstrumentCore>>

Create a new synchronous instrument implementation.

fn new_async_instrument(
    &self,
    descriptor: Descriptor,
    runner: Option<AsyncRunner>
) -> Result<Arc<dyn AsyncInstrumentCore>>

Create a new asynchronous instrument implementation.

Runner is None if used in batch as the batch runner is registered separately.

fn new_batch_observer(&self, runner: AsyncRunner) -> Result<()>

Register a batch observer
