type TimeUtil ¶ added in v0.1.3

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

时间工具，在测试中，很多时候需要控制 time.Now() 产生的时间例如：设置当前时间为 3天后，用正常时间的 1/10 行进时间

func NewTimeUtil ¶ added in v0.1.3

func NewTimeUtil() *TimeUtil

func (*TimeUtil) Add ¶ added in v0.1.3

func (t *TimeUtil) Add(duration time.Duration)

func (*TimeUtil) Now ¶ added in v0.1.3

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

func (*TimeUtil) SetDebug ¶ added in v0.1.3

func (t *TimeUtil) SetDebug(isDebug bool)

func (*TimeUtil) SetNow ¶ added in v0.1.3

func (t *TimeUtil) SetNow(now time.Time)

type WaitTimeout ¶ added in v0.2.1

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

WaitTimeout 带有超时的 WaitGroup，避免了 wg.Wait() 可能引起的 blocked forever，协程永远无法被释放

func NewWaitTimeout ¶ added in v0.2.1

func NewWaitTimeout() *WaitTimeout

NewWaitTimeout 必须使用 NewWaitTimeout 实例化 WaitTimeout

func (*WaitTimeout) Add ¶ added in v0.2.1

func (wt *WaitTimeout) Add(n int32) *WaitTimeout

func (*WaitTimeout) Done ¶ added in v0.2.1

func (wt *WaitTimeout) Done()

func (*WaitTimeout) Wait ¶ added in v0.2.1

func (wt *WaitTimeout) Wait(timeout time.Duration) chan bool

Wait, 等待过程外置，外部使用时，可以先获取 chan, 在释放完可能存在的锁后，进入 <-chan 环节，避免等待时间内持有锁一个 WaitTimeout 只能使用一次，wt.Done() 后会 close(wt.doneChan)，再次 wt.Done() 会触发 panic

type Watcher ¶ added in v0.2.2

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

func NewWatcher ¶ added in v0.2.2

func NewWatcher() *Watcher

func (*Watcher) Notify ¶ added in v0.2.2

func (w *Watcher) Notify()

func (*Watcher) Watch ¶ added in v0.2.2

func (w *Watcher) Watch(timeout time.Duration) chan bool
