Functions ¶
func BackoffUntil ¶
func BackoffUntil(ctx context.Context, f func(), backoff BackoffManager, sliding bool)
BackoffUntil 不断的运行 f 函数，运行间隔由BackoffManager 提供, 直到ctx.Done 返回. sliding 为true 则计算f函数运行时间.sliding 为false 则忽视f运行时间.
func NonSlidingUntil ¶
NonSlidingUntil 不断的以间隔period运行f, 直到ctx.Done 返回. 忽视f函数运行时间.
Types ¶
type BackoffManager ¶
BackoffManager 接口可以提供 Backoff 方法， Backoff 返回一个Timer 确定要等待的时间
func NewSimpleBackoffManager ¶
func NewSimpleBackoffManager(period time.Duration) BackoffManager
NewSimpleBackoffManager 返回一个简单的BackoffManager 以固定时间间隔返回Backoff
