Types

type Averager

type Averager interface {
	// Observe the value at the given time
	Observe(value float64, currentTime time.Time)

	// Read returns the average of the provided values.
	Read() float64
}

Averager tracks a continuous time exponential moving average of the provided values.

func NewAverager(
	initialPrediction float64,
	halflife time.Duration,
	currentTime time.Time,
) Averager

func NewSyncAverager

func NewSyncAverager(averager Averager) Averager
