尝试编译此构造函数时出现错误

如何解决尝试编译此构造函数时出现错误

我有一个带有构造函数的类，但编译失败并显示错误：

错误：使用已删除的函数'std::atomic::atomic(const std::atomic&)'

我正在努力理解这个错误意味着什么。我一直在尝试将一些代码从使用 tbb::atomic 更新为使用 std::atomic，并且此错误之前没有出现在 tbb::atomic 中。

让编译器感到不安的代码是：

#include <boost/aligned_storage.hpp>

template <typename T>
class Holder<T,true>
{
public:
  //! Construct a value (there mustn't be one already)
  template <typename ARG>
  void Construct(const ARG &arg) { new(Raw()) T(arg); }

private:
  typename boost::aligned_storage<sizeof(T),boost::alignment_of<T>::value>::type impl;
  void *Raw() { return &impl; }
};

特别是那一行：

void Construct(const ARG &arg) { new(Raw()) T(arg); }

如果有人能帮助我了解正在发生的事情，我将不胜感激。
