Functions

func PutFast

func PutFast(f *Fast)

PutFast puts hf to the pool.

hf cannot be used after this call.

Types

type Fast

type Fast struct {
	// contains filtered or unexported fields
}

Fast is a fast histogram.

It cannot be used from concurrently running goroutines without external synchronization.

func GetFast

func GetFast() *Fast

GetFast returns a histogram from a pool.

func NewFast

func NewFast() *Fast

NewFast returns new fast histogram.

func (*Fast) Quantile

func (f *Fast) Quantile(phi float64) float64

Quantile returns the quantile value for the given phi.

func (*Fast) Quantiles

func (f *Fast) Quantiles(dst, phis []float64) []float64

Quantiles appends quantile values to dst for the given phis.

func (*Fast) Reset

func (f *Fast) Reset()

Reset resets the histogram.

func (*Fast) Update

func (f *Fast) Update(v float64)

Update updates the f with v.
