std::string を含む C クラスを安全にシリアル化および逆シリアル化する方法

class MyClass {
    int height;
    int width;
    std::string name;

public:
    std::ostream& operator<<(std::ostream& out) const {
        out << height << ',' << width << ',' << name.size() << ',' << name;
        return out;
    }
    std::istream& operator>>(std::istream& in) {
        int len = 0;
        char comma;
        in >> height >> comma >> width >> comma >> len >> comma;
        if (len) {
            std::vector<char> tmp(len);
            in.read(tmp.data(), len);
            name.assign(tmp.data(), len);
        }
        return in;
    }
};

MyClass obj;
obj.height = 10;
obj.width = 15;
obj.name = "MyClass";

// Serialize to file
std::ofstream outfile("myclass.dat");
outfile << obj;
outfile.close();

// Deserialize from file
std::ifstream infile("myclass.dat");
infile >> obj;
infile.close();
