MCache library

go-mcache - this is a fast key:value storage Its major advantage is that, being essentially a thread-safe

map[string]interface{}

with expiration times, it doesn't need to serialize, and quick removal of expired keys

Installation

~ $ go get github.com/OrlovEvgeny/go-mcache

Example a Pointer value (vary fast method)

var MCache *mcache.CacheDriver

type User {
	Name string
	Age uint
	Bio string
}

func main() {
	MCache = mcache.StartInstance()
	
	key := "key1"
	
	user := new(User)
	user.Name = "John"
	user.Age = 20
	user.Bio = "gopher"
	//args - key, &value, ttl
	MCache.SetPointer(key, user, time.Minute*20)
	if err != nil {
		log.Println("MCACHE SET ERROR: ", err)
	}
	
	if pointer, ok := mcache.GetPointer(key); ok {
		if objUser, ok := pointer.(*User); ok {
			fmt.Printf("User name: %s, Age: %d, Bio: %s\n", objUser.Name, objUser.Age, objUser,Bio)
		}
	} else {
		log.Println("Cache by key: %s not found", key)
	}
}

Example serialize and deserialize value

var MCache *mcache.CacheDriver

type User {
	Name string
	Age uint
	Bio string
}

func main() {
	MCache = mcache.StartInstance()
	
	key := "key1"
	
	userSet := new(User)
	userSet.Name = "John"
	userSet.Age = 20
	userSet.Bio = "gopher"
	
	//args - key, &value, ttl
	MCache.Set(key, userSet, time.Minute*20)
	if err != nil {
		log.Println("MCACHE SET ERROR: ", err)
	}
	
	
	var userGet User
	if ok := mcache.Get(key, &userGet); ok {
            fmt.Printf("User name: %s, Age: %d, Bio: %s\n", userGet.Name, userGet.Age, userGet,Bio)
    } else {
    	log.Println("Cache by key: %s not found", key)
    }
}
