1. map类型缓存

提供间隔时间对数据进行过期清理
可手动开启/停止清理能力
可手动清除全部缓存
缓存持久化
...

接口

// IsExpired judge whether the data is expired
IsExpired(key string) (bool, error)
// DeleteExpired delete all expired data
DeleteExpired()

// StartGc start gc
// After the expiration time is set, GC will be started automatically without manual GC
StartGc() error
// StopGc stop gc
StopGc() error

// Get data
// When the data does not exist or expires, it will return nonexistence（false）
Get(key string) (E, bool)
// GetAndDelete get data and delete by key
GetAndDelete(key string) (E, bool)
// GetAndExpired  get data and expire by key
// It will be deleted at the next clearing. If the clearing capability is not enabled, it will never be deleted
GetAndExpired(key string) (E, bool)

// Delete delete data by key
Delete(key string) (E, bool)


// Set  data by key，it will overwrite the data if the key exists
Set(key string, value E)
// Add data，Cannot add existing data
// To override the addition, use the set method
Add(key string, value E) error
// Clear remove all data
Clear()
// Keys get all keys
Keys() []string

初始化可选项

// 设置过期时间
SetExpirationTime(expiration time.Duration)

// 设置gc时间间隔
SetGcInterval(gcInterval time.Duration)

// 开启持久化（需要指定持久化文件名前缀）
SetEnablePersistence(name string)

// 设置持久化策略（目前只支持一种FFB：全量保存）
SetPersistencePolicy(policy Persistence)

// 设置持久化文件保存路径
SetPersistencePath(path string)

使用

示例

func Test(t *testing.T) {{
    c,err := cache.NewMapCache[int]()
    if err != nil {
        fmt.Println("err:", err)
        return
    }
    c.Set("1", 1)
    fmt.Println(c.Get("1"))
}

输出

1 true
