Types ¶

type Clock ¶

type Clock interface {
	Now() time.Time
	Since(time.Time) time.Duration
	After(d time.Duration) <-chan time.Time
	Sleep(d time.Duration)
	Tick(d time.Duration) <-chan time.Time
}

Clock allows for injecting fake or real clocks into code that needs to do arbitrary things based on time.

type FakeClock ¶

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

FakeClock implements Clock, but returns an arbitrary time.

func NewFakeClock ¶

func NewFakeClock(t time.Time) *FakeClock

func (*FakeClock) After ¶

func (f *FakeClock) After(d time.Duration) <-chan time.Time

Fake version of time.After(d).

func (*FakeClock) HasWaiters ¶

func (f *FakeClock) HasWaiters() bool

Returns true if After has been called on f but not yet satisfied (so you can write race-free tests).

func (*FakeClock) Now ¶

func (f *FakeClock) Now() time.Time

Now returns f's time.

func (*FakeClock) SetTime ¶

func (f *FakeClock) SetTime(t time.Time)

Sets the time.

func (*FakeClock) Since ¶

func (f *FakeClock) Since(ts time.Time) time.Duration

Since returns time since the time in f.

func (*FakeClock) Sleep ¶

func (f *FakeClock) Sleep(d time.Duration)

func (*FakeClock) Step ¶

func (f *FakeClock) Step(d time.Duration)

Move clock by Duration, notify anyone that's called After or Tick

func (*FakeClock) Tick ¶

func (f *FakeClock) Tick(d time.Duration) <-chan time.Time

type IntervalClock ¶

type IntervalClock struct {
	Time     time.Time
	Duration time.Duration
}

IntervalClock implements Clock, but each invocation of Now steps the clock forward the specified duration

func (*IntervalClock) After ¶

func (*IntervalClock) After(d time.Duration) <-chan time.Time

Unimplemented, will panic. TODO: make interval clock use FakeClock so this can be implemented.

func (*IntervalClock) Now ¶

func (i *IntervalClock) Now() time.Time

Now returns i's time.

func (*IntervalClock) Since ¶

func (i *IntervalClock) Since(ts time.Time) time.Duration

Since returns time since the time in i.

func (*IntervalClock) Sleep ¶

func (*IntervalClock) Sleep(d time.Duration)

func (*IntervalClock) Tick ¶

func (*IntervalClock) Tick(d time.Duration) <-chan time.Time

Unimplemented, will panic. TODO: make interval clock use FakeClock so this can be implemented.

type RealClock ¶

type RealClock struct{}

RealClock really calls time.Now()

func (RealClock) After ¶

func (RealClock) After(d time.Duration) <-chan time.Time

Same as time.After(d).

func (RealClock) Now ¶

func (RealClock) Now() time.Time

Now returns the current time.

func (RealClock) Since ¶

func (RealClock) Since(ts time.Time) time.Duration

Since returns time since the specified timestamp.

func (RealClock) Sleep ¶

func (RealClock) Sleep(d time.Duration)

func (RealClock) Tick ¶

func (RealClock) Tick(d time.Duration) <-chan time.Time
