c++ - 如何将参数列表存储到 vector ？

Question

如何将可变参数构造函数参数存储到 vector ？
我失败的尝试示例:

class Combo 
{
public:
   template <class... Args>
   Combo(Args... args) 
   {
      // this->keys_.push_back(args...);

      // this->keys_.push_back(args)...;

      // this->keys_.push_back(std::forward<Args>(args...));

      //for (uint8_t arg : args...)
      //  this->keys_.push_back(arg);

      // ???
   }

private:
   std::vector<uint8_t> keys_;
};

Answer 1

C++11

for(auto &&i: {args...}) keys.push_back(std::move(i));

C++17

(keys.push_back(args), ...);

哦，对不起，我错过了显而易见的:

template<class... Args> Combo(Args... args): keys_{uint8_t(args)...} {}
