advanced patterns with std::atomic and Custom Object Types in C++11
I'm trying to implement I'm working with a strange scenario when trying to use `std::atomic` with a custom object type in C++11. My custom type, `MyData`, contains a `std::string`, and I assumed that using `std::atomic` would work seamlessly. However, when I try to assign a new value to my atomic variable, I get a compilation behavior. Here's a simplified version of my code: ```cpp #include <iostream> #include <atomic> #include <string> class MyData { public: std::string value; MyData(const std::string& v) : value(v) {} }; std::atomic<MyData> myAtomicData(MyData("Initial")); // behavior occurs here int main() { MyData newData("Updated"); myAtomicData.store(newData); // Expected to work std::cout << myAtomicData.load().value << std::endl; return 0; } ``` The behavior I receive is: `behavior: no matching function for call to 'std::atomic<MyData>::atomic(const MyData&)'`. I understand that `std::atomic` requires the type to be trivially copyable, but I thought using a `std::string` would still be valid because of the standard library's support for it. I've tried using `std::shared_ptr<MyData>` instead, but that introduces its own complications with memory management and reference counting. Is there any way to use `std::atomic` effectively with a custom object type, or should I change my approach altogether? Any suggestions would be greatly appreciated! I recently upgraded to Cpp latest. I appreciate any insights! I'm on Windows 11 using the latest version of Cpp. What are your experiences with this?
