Seed is the fixed random seed used for reproducible benchmark inputs.

Functions

func ConsumeBytes

func ConsumeBytes(data []byte)

ConsumeBytes mixes a byte slice into the global sink.

func ConsumeUint64

func ConsumeUint64(value uint64)

ConsumeUint64 mixes a value into the global sink.

func MBPerSecond

func MBPerSecond(processed int64, elapsed time.Duration) float64

MBPerSecond calculates MiB/s throughput.

func MedianDuration

func MedianDuration(samples []time.Duration) time.Duration

MedianDuration returns the median sample.

func MedianFloat64

func MedianFloat64(samples []float64) float64

MedianFloat64 returns the median float64 sample.

func MedianInt64

func MedianInt64(samples []int64) int64

MedianInt64 returns the median int64 sample.

func NewRand

func NewRand() *rand.Rand

NewRand returns a deterministic random source.

func RandomBytes

func RandomBytes(size int) []byte

RandomBytes returns a deterministic byte slice of the requested size.

func RandomInt64Slice

func RandomInt64Slice(count int) []int64

RandomInt64Slice returns a deterministic int64 slice.

func SinkValue

func SinkValue() uint64

SinkValue returns the current sink value.
