)
func main() {
cache := reference.NewTypedCache(reference.CacheOptions{
MaxSize: 2,
ExpireAfterRead: 2 * time.Minute,
ExpireAfterWrite: time.Minute,
RemovalListeners: []reference.RemovalListener{
func(notification reference.RemovalNotification) {
fmt.Printf("Entry removed due to %s\n", notification.Reason)
},
},
Load: func(key string) (int64, error) {
fmt.Printf("Loading key %s\n", key)
return int64(len(key)), nil

})
cache.Put("a", 1)
var val1 int64
val1, _ = cache.Get("a")
