serialization - 如何序列化 boost::uuids::uuid

Question

我目前正在项目中使用 boost::uuids::uuid，并且我想序列化包含 boost::uuids::uuid 的对象。我尝试了下面的简单示例，但出现错误:

/usr/include/boost/archive/basic_text_oprimitive.hpp:92: 错误: '((boost::archive::basic_text_oprimitive >*)this)->boost::archive 中的 'operator<<' 不匹配::basic_text_oprimitive >::os << t'

如果有人能帮助我，我真的很感激。

#include <fstream>
#include <boost/uuid/uuid.hpp>
#include <boost/uuid/uuid_generators.hpp>
#include <boost/uuid/uuid_serialize.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>

class classA {
public:
    classA() : id(boost::uuids::random_generator()()) {}
private:
    friend class boost::serialization::access;
    boost::uuids::uuid id;
    template <class Archive>
    void serialize(Archive& ar, const unsigned int version) {
        ar & id;
    }
};

int main(void) {
    classA a;
    std::ofstream ofs("uuid.txt");
    boost::archive::text_oarchive oa(ofs);
    oa << a;
    ofs.close();
    return 0;
}

包括<boost/uuid/uuid_serialize.hpp>启用 uuid 的序列化。 http://www.boost.org/doc/libs/1_42_0/libs/uuid/uuid.html#boost/uuid/uuid_serialize.hpp
