使用boost :: archive与boost :: iostreams压缩数据

struct X
{
    X() {}

    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        ar & compression;
        if(compression == 0)
        {
            ar & data;
        }
        else if(compression == 1)
        {
            // use boost::iostream compression
            // facilities to serialize data
        }
    }

    int compression;
    std::vector<int> data;
};
