pub struct DefaultAggregationSelector { /* private fields */ }
Available on crate feature metrics only.
Expand description

The default aggregation and parameters for an instrument of InstrumentKind.

This AggregationSelector uses the following selection mapping per the spec:

  • Counter ⇨ Sum
  • Observable Counter ⇨ Sum
  • UpDownCounter ⇨ Sum
  • Observable UpDownCounter ⇨ Sum
  • Observable Gauge ⇨ LastValue
  • Histogram ⇨ ExplicitBucketHistogram
