How do I serialize and deserialize contents with std::set in multithreaded code?

In a multithreaded C++ application, serializing and deserializing a `std::set` involves ensuring that access to the set is appropriately synchronized across threads to prevent data races.

The following example demonstrates how to use mutexes to protect a `std::set` and serialize/deserialize its contents to/from a string format. This is useful for safe communication between threads or for persistence.


        #include 
        #include 
        #include 
        #include 
        #include 

        class ThreadSafeSet {
        public:
            void insert(int value) {
                std::lock_guard<:mutex> lock(mutex_);
                data_.insert(value);
            }

            std::string serialize() {
                std::lock_guard<:mutex> lock(mutex_);
                std::ostringstream oss;
                for (const auto& value : data_) {
                    oss << value << ",";
                }
                std::string result = oss.str();
                if (!result.empty()) {
                    result.pop_back(); // Remove trailing comma
                }
                return result;
            }

            void deserialize(const std::string& str) {
                std::lock_guard<:mutex> lock(mutex_);
                data_.clear();
                std::istringstream iss(str);
                std::string token;
                while (std::getline(iss, token, ',')) {
                    data_.insert(std::stoi(token));
                }
            }

        private:
            std::set data_;
            std::mutex mutex_;
        };

        void sampleUsage() {
            ThreadSafeSet tsSet;
            tsSet.insert(1);
            tsSet.insert(2);
            tsSet.insert(3);

            std::string serialized = tsSet.serialize();
            std::cout << "Serialized: " << serialized << std::endl;

            tsSet.deserialize("4,5,6");
            std::cout << "Deserialized and Updated." << std::endl;
        }

        int main() {
            std::thread t1(sampleUsage);
            std::thread t2(sampleUsage);

            t1.join();
            t2.join();

            return 0;
        }
