```go
func New(config ...Config) Storage

var ErrNotExist = errors.New("key does not exist")

func (s *Storage) Get(key string) ([]byte, error)
func (s *Storage) Set(key string, val []byte, exp time.Duration) error
func (s *Storage) Delete(key string) error

You can use the following possibilities to create a storage:
```go
// Initialize default config
store := redis.New()

// Initialize custom config
store := redis.New(redis.Config{
	Host:     "127.0.0.1",
	Port:     6379,
	Username: "",
	Password: "",
	Database: 0,
	Clear:    false,
})
```

### Config
```go
type Config struct {
	// Host name where the DB is hosted
	//
	// Optional. Default is "127.0.0.1"
