没有使用Golang的泛型的类型断言的解决方案？

int, uint, int8, uint8 ....

Then I have a plugin in template like this:

f["UNIX2STR"] = func(t interface{}, f string) string {
        switch t.(type) {
        case int:
            return time.Unix(int64(t.(int)), 0).Format(f)
        case uint:
            return time.Unix(int64(t.(uint)), 0).Format(f)
        case uint8:
            return time.Unix(int64(t.(uint8)), 0).Format(f)
        case *int:
            return time.Unix(int64(*t.(*int)), 0).Format(f)
        case *uint:
            return time.Unix(int64(*t.(*uint)), 0).Format(f)
        case *uint8:
            return time.Unix(int64(*t.(*uint8)), 0).Format(f)
        .....
        default:
            return ""
        }
        // return time.Unix(int64(t), 0).Format(f)
    }

int64

interface{}
