# agingMap

 

基于 sync.Map 的一个带过期时间的 Map

```go

go get -u github.com/520MianXiangDuiXiang520/agingMap

```

## 使用

```go

packege main

import (

    "github.com/520MianXiangDuiXiang520/agingMap"

    "time"

    "fmt"

)

func main() {

    // 每秒遍历 50%，过期删除

    // am := NewAgingMap()

    

    // 惰性删除

    // am := NewWithLazyDelete()

    

    am := NewBaseAgingMap(time.Second * 5, 0.7)

    keyChan := make(chan int64, 10)

    go func() {

        for {

            key := time.Now().UnixNano()

            keyChan <- key

            am.Store(key, 1, time.Second) 

        }

    }()

    for {

        key := <- keyChan

        val, ok := am.Load(key)

        if ok {

            fmt.Println(val)

        }

    }

}

```
