Types

type Clock

type Clock interface {
	Now() time.Time
}

Clock provides an interface to implement method for getting current time.

type DefaultClock

type DefaultClock struct{}

DefaultClock is an implementation of Clock interface.

func (*DefaultClock) Now

func (t *DefaultClock) Now() time.Time

Now returns current time.

type DefaultRand

type DefaultRand struct{}

DefaultRand is an implementation of Rand interface.

func (*DefaultRand) Float64

func (r *DefaultRand) Float64() float64

Float64 returns, as a float64, a pseudo-random number in [0.0,1.0) from the default Source.

func (*DefaultRand) Int63n

func (r *DefaultRand) Int63n(n int64) int64

Int63n returns, as an int64, a non-negative pseudo-random number in [0,n) from the default Source.

func (*DefaultRand) Intn

func (r *DefaultRand) Intn(n int) int

Intn returns, as an int, a non-negative pseudo-random number in [0,n) from the default Source.

type MockClock

type MockClock struct {
	NowTime int64
}
