In the onEvict function, make the "value" variable be of type interface{} and type-assert it to be CacheItem, then pass onEvict w/o any type-conversions to cache.Set(): func onEvict(key string, value interface{}) { ci := value.(CacheItem) fmt.Println(key, ci.v) } ... cache.Set("key1", t, onEvict) Playground link: <https://play.golang.org/p/75OUF5W344> -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
