I'm looking a way to get the unique id of a class. I'm able to do this in C++ using type_info::hash_code(). void function(T) { auto id = typeid(T).getHash(); // Something like this? // I know i could write this but seems ugly to me :/ auto id = typeid(string).getHash(typeid(T).name); // Or maybe even better. auto id = typeid(T).id; // ID is not a number but a class for storing }
