Types

type StatsAggregate

type StatsAggregate struct {
	Average, Min, Max float64
	Count             int
}

StatsAggregate represents the computed aggregation of a collection of stats

func Aggregate

func Aggregate(stats []*stat.Stat) (aggregate StatsAggregate)

Aggregate aggregates a collection of statistics, returning the average, min and max. Aggregate only examines the 'Value' property of a stat, and ignores all other properties (i.e. Name)

func AppendStatsAggregate

func AppendStatsAggregate(a, b StatsAggregate) (aggregate StatsAggregate)

AppendStatsAggregate appends new StatsAggregate values to an existing one, safely computing new values in the process. This function enables aggregates to be combined without re-computing all the original values
