Functions

Create a new default ArrayAggregator

An aggregator to calculate quantile

Create a new histogram for the given descriptor with the given boundaries

Create a new LastValueAggregator

min_max_sum_count

Create a new MinMaxSumCountAggregator

RangeTest is a common routine for testing for valid input values. This rejects NaN values. This rejects negative values when the metric instrument does not support negative values, including monotonic counter metrics and absolute ValueRecorder metrics.

Create a new sum aggregator.
