How do I serialize and deserialize contents with std::deque in performance-sensitive code?

In performance-sensitive C++ applications, serializing and deserializing a `std::deque` efficiently is crucial for maintaining speed and resource management. This section will cover the best practices for achieving high-performance serialization and deserialization of `std::deque` objects.

Keywords: C++, std::deque, serialization, deserialization, performance-sensitive code, high-performance coding.

Description: Learn how to efficiently serialize and deserialize std::deque in C++ to maintain performance in sensitive applications.


        // Example of Serializing and Deserializing a std::deque
        #include 
        #include 
        #include 

        // Function to serialize a std::deque
        template
        void serialize(std::deque& d, std::ostream& os) {
            size_t size = d.size();
            os.write(reinterpret_cast(&size), sizeof(size));
            for (const auto& item : d) {
                os.write(reinterpret_cast(&item), sizeof(T));
            }
        }

        // Function to deserialize into a std::deque
        template
        void deserialize(std::deque& d, std::istream& is) {
            size_t size;
            is.read(reinterpret_cast(&size), sizeof(size));
            d.resize(size);
            for (auto& item : d) {
                is.read(reinterpret_cast(&item), sizeof(T));
            }
        }

        int main() {
            std::deque myDeque = {1, 2, 3, 4, 5};

            // Serialize the deque
            std::ofstream outFile("deque.bin", std::ios::binary);
            serialize(myDeque, outFile);
            outFile.close();

            // Deserialize the deque
            std::deque newDeque;
            std::ifstream inFile("deque.bin", std::ios::binary);
            deserialize(newDeque, inFile);
            inFile.close();

            // Display the deserialized content
            for (const int& value : newDeque) {
                std::cout << value << " ";
            }
            return 0;
        }
