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
}

Have you tried toHash()?

I Think that would return the hash of every member of a class, rather than just the hash of the class name
