Functions

func ResolveNextTimePoint

func ResolveNextTimePoint(nowSec int64, resolution int64) int64

ResolveNextTimePoint returns the next time point.

Types

type TimeSourceFunc

type TimeSourceFunc func() int64

TimeSourceFunc is a function which gets an understanding of time in seconds resolution back.

type UnixTimestampPrng

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

UnixTimestampPrng is a pseudo random number generator using the Unix time in seconds to derive a random number from.

func NewUnixTimestampPRNG

func NewUnixTimestampPRNG(resolution int64, timeSourceFunc ...TimeSourceFunc) *UnixTimestampPrng

NewUnixTimestampPRNG creates a new Unix timestamp based pseudo random number generator using the given resolution. The resolution defines at which second interval numbers are generated.

func (*UnixTimestampPrng) C

func (utrng *UnixTimestampPrng) C() <-chan float64

C returns the channel from which random generated numbers can be consumed from.

func (*UnixTimestampPrng) Start

func (utrng *UnixTimestampPrng) Start()

Start starts the Unix timestamp pseudo random number generator by examining the interval and then starting production of numbers after at least interval seconds plus delta of the next resolution time have elapsed.

func (*UnixTimestampPrng) Stop

func (utrng *UnixTimestampPrng) Stop()

Stop stops the Unix timestamp pseudo random number generator.
