Structs

AggregationKind

LastValue

LastValue returns the latest value that was aggregated.

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.
