c++ - boost::serialize 和 std::chrono::system_clock::time_point

Question

我正在尝试使用 boost::serialize 序列化一个包含 std::chrono::system_clock::time_point 的类。

template <class Archive> void serialize(Archive& ar, unsigned int version) {
    ar & timePoint_;
}

但是我得到了错误:

错误 1 ​​error C2039: 'serialize' : is not a member of 'std::chrono::time_point<_Clock>' c:\boost_1_54_0\boost\serialization\access.hpp 118

我该如何解决这个问题？

Answer 1

使用

boost::serialization::make_binary_object(void * t, size_t size);

来自boost/serialization/binary_object.hpp 可以这样使用:

std::chrono::system_clock::time_point tp;
ar & boost::serialization::make_binary_object(&tp, sizeof(tp));
