Aggregation returns an interface for reading the state of this aggregator.
func (c *Aggregator) Kind() aggregation.Kind
Kind returns aggregation.SumKind.
func (c *Aggregator) Merge(oa export.Aggregator, desc *otel.Descriptor) error
Merge combines two counters by adding their sums.
func (c *Aggregator) Subtract(opAgg, resAgg export.Aggregator, descriptor *otel.Descriptor) error
func (c *Aggregator) Sum() (otel.Number, error)
Sum returns the last-checkpointed sum. This will never return an error.
func (c *Aggregator) SynchronizedMove(oa export.Aggregator, _ *otel.Descriptor) error

func (c *Aggregator) Update(_ context.Context, number otel.Number, desc *otel.Descriptor) error
Update atomically adds to the current value.
