Available on crate feature metrics only.

Metrics aggregation

Structs

• AggregationKind
  A short name for the Aggregator that produces an Aggregation.
• Buckets
  Buckets represent histogram buckets boundaries and counts.

Enums

• Temporality
  Temporality indicates the temporal aggregation exported by an exporter. These bits may be OR-d together when multiple exporters are in use.

Traits

• Aggregation
  An interface returned by an Aggregator containing an interval of metric data.
• Count
  Count returns the number of values that were aggregated.
• Histogram
  Histogram returns the count of events in pre-determined buckets.
• LastValue
  LastValue returns the latest value that was aggregated.
• Max
  Sum returns an aggregated max.
• Min
  Sum returns an aggregated min.
• Sum
  Sum returns an aggregated sum.
• TemporalitySelector
  TemporalitySelector is a sub-interface of Exporter used to indicate whether the Processor should compute Delta or Cumulative Aggregations.

Functions

• constant_temporality_selector
  Returns an TemporalitySelector that returns a constant Temporality.
• cumulative_temporality_selector
  Returns an TemporalitySelector that always returns Temporality::Cumulative.
• delta_temporality_selector
  Returns an TemporalitySelector that always returns Temporality::Delta.
• stateless_temporality_selector
  Returns a TemporalitySelector that always returns the cumulative Temporality to avoid long-term memory requirements.
