type NameExample interface {
GetLoopLock(ctx context.Context, key string, options ...redsync.Option) (*redsync.Mutex, error)
GetLock(ctx context.Context, key string, options ...redsync.Option) (*redsync.Mutex, error)
// 封装了锁的获取、看门狗自动续期、业务执行及释放逻辑
WatchDogLock(ctx context.Context, key string, expiry time.Duration, task func(ctx context.Context) error, options ...redsync.Option) error
WatchDogLoopLock(ctx context.Context, key string, expiry time.Duration, task func(ctx context.Context) error, options ...redsync.Option) error
Set(ctx context.Context, key string, data interface{}, duration time.Duration) error
Get(ctx context.Context, key string) (interface{}, error)
