編譯序列化boost :: unordered_set錯誤

Question

首先，現在boost :: serialization是否支持unordered_set？我沒有找到頭文件boost/serialization/unordered_set.hpp。

這裏是我試圖執行代碼：

namespace boost { 
namespace serialization{ 

template<class Archive, typename T, typename H, typename P, typename A> 
void save(Archive &ar, 
      const unordered::unordered_set<T,H,P,A> &s, const unsigned int) { 
    vector<T> vec(s.begin(),s.end()); 
    ar<<vec;  
} 
template<class Archive, typename T, typename H, typename P, typename A> 
void load(Archive &ar, 
      unordered::unordered_set<T,H,P,A> &s, const unsigned int) { 
    vector<T> vec; 
    ar>>vec; 
    std::copy(vec.begin(),vec.end(),  
       std::inserter(s,s.begin())); 
} 

template<class Archive, typename T, typename H, typename P, typename A> 
void serialize(Archive &ar, 
       unordered::unordered_set<T,H,P,A> &s, const unsigned int version) { 
    boost::serialization::split_free(ar,s,version); 
} 

} 
} 

以下是錯誤：

'class std::vector<int, std::allocator<int> >' has no member named 'serialize' 

另外，我還有以下代碼警告：

boost::archive::text_oarchive(ss)<<s1; 

Warning:comparison between signed and unsigned integer expressions [-Wsign-compare] 

我不確定是否可以忽略它。

要回答你的第一個問題，沒有序列化支持形式的序列化boost.unordered容器的boost庫。
