Usage

Sweet memories is data cache. If you want to save data for a spesific time without any caching tools, you can simply use sweet memories. Note: you have to consider your memory first.

Example Case

If you want to not get data from database everytime, you can simply use sweet memories. Use one sweet memories Object to save any kind of data! One object, one responsibility.

Example

	var DataTemporary *sweetmemories.Memory

	func init(){
		DataTemporary = sweetmemories.New()
	}

	data := []Data{}
	if DataTemporary.IsForget() { // if cache is nil
		DataTemporary.Save(getData(), 600*time.Second) //Fill your cache memory
	}
	if dt, ok := DataTemporary.GetMemory().([]Data); ok {
			data = dt
	}

func getData() []Data {
	result := []Data{}
	results, err := db.Query("SELECT product_id, product_name, product_cat FROM product")
	if err != nil {
		return result
	}

	for results.Next() {
		var id int
		var cat int
		var name string

		err = results.Scan(&id, &name, &cat)
		if err != nil {
			panic(err.Error())
		}
		result = append(result, Data{
			ProductID:   id,
			ProductCat:  cat,
			ProductName: name,
		})
	}
	return result
}

	ProductID   int    `json:"product_id"`
