timer是高性能定时器库
|
|||
|
|
## feature
|
|||
|
|
* 支持一次性定时器
|
|||
|
|
* 支持周期性定时器
|
|||
|
|
* 支持多种数据结构后端，最小堆，5级时间轮
|
|||
|
|
|
|||
|
|
## 一次性定时器
|
|||
|
|
```go
|
|||
|
|
import (
|
|||
|
|
"github.com/antlabs/timer"
|
|||
|
|
"log"
|
|||
|
|
)
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
tm := timer.NewTimer()
|
|||
|
|
|
|||
|
|
tm.AfterFunc(1*time.Second, func() {
|
|||
|
|
log.Printf("after\n")
|
|||
|
|
})
|
|||
|
|
|
|||
|
|
tm.AfterFunc(10*time.Second, func() {
|
|||
|
|
log.Printf("after\n")
|
|||
|
|
})
|
|||
|
|
tm.Run()
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
## 周期性定时器
|
|||
|
|
```go
|
|||
|
|
import (
|
|||
|
|
"github.com/antlabs/timer"
|
|||
|
|
"log"
|
|||
|
|
)
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
tm := timer.NewTimer()
|
|||
|
|
|
|||
|
|
tm.ScheduleFunc(1*time.Second, func() {
|
|||
|
|
log.Printf("schedule\n")
|
|||
|
|
})
|
|||
|
|
|
|||
|
|
tm.Run()
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
## 自定义周期性定时器
|
|||
|
|
实现时间翻倍定时的例子
|
|||
|
|
```go
|
|||
|
|
type curstomTest struct {
|
|||
|
|
count int
|
|||
|
|
}
|
|||
|
|
// 只要实现Next接口就行
|
|||
|
|
func (c *curstomTest) Next(now time.Time) (rv time.Time) {
|
|||
|
|
rv = now.Add(time.Duration(c.count) * time.Millisecond * 10)
|
|||
|
|
c.count++
|
|||
|
|
return
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
tm := timer.NewTimer(timer.WithMinHeap())
|
|||
|
|
node := tm.CustomFunc(&curstomTest{count: 1}, func() {
|
|||
|
|
log.Printf("%v\n", time.Now())
|
|||
|
|
})
|
|||
|
|
tm.Run()
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
## 取消某一个定时器
|
|||
|
|
```go
|
|||
|
|
import (
|
|||
|
|
"log"
|
|||
|
|
"time"
|
|||
|
|
|
|||
|
|
"github.com/antlabs/timer"
|
|||
|
|
)
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
|
|||
|
|
tm := timer.NewTimer()
|
|||
|
|
|
|||
|
|
// 只会打印2 time.Second
|
|||
|
|
tm.AfterFunc(2*time.Second, func() {
|
|||
|
|
log.Printf("2 time.Second")
|
|||
|
|
})
|
|||
|
|
|
|||
|
|
// tk3 会被 tk3.Stop()函数调用取消掉
|
|||
|
|
tk3 := tm.AfterFunc(3*time.Second, func() {
|
|||
|
|
log.Printf("3 time.Second")
|
|||
|
|
})
|
|||
|
|
|
|||
|
|
tk3.Stop() //取消tk3
|
|||
|
|
|
|||
|
|
tm.Run()
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
## 选择不同的的数据结构
|
|||
|
|
```go
|
|||
|
|
import (
|
|||
|
|
"github.com/antlabs/timer"
|
|||
|
|
"log"
|
|||
|
|
)
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
tm := timer.NewTimer(timer.WithMinHeap())// 选择最小堆，默认时间轮
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
