• Simple caching with auto type assertion included.
• In memory file cache index to avoid unneeded I/O.
• Msgpack based binary serialization using msgpack library for file caching.

Quickstart

func ExampleCache() {
	cache := cachita.Memory()
	err := cache.Put("cache_key", "some data", 1*time.Minute)
	if err != nil {
		panic(err)
	}

	if cache.Exists("cache_key") {
		//do something
	}

	var holder string
	err = cache.Get("cache_key", &holder)
	if err != nil && err != cachita.ErrNotFound {
		panic(err)
	}

	fmt.Printf("%s", holder) //prints "some data"

	err = cache.Invalidate("cache_key")
	if err != nil {
		panic(err)
	}

	//Output: some data

}
