Modern C++23/26: from concepts to coroutines in high-performance services

  • C++23 and C++26 bring features enhancing performance and productivity in high-performance services, such as real-time analytics and game servers.
  • Concepts in C++ define requirements for template parameters, improving error handling and compiler optimizations.
  • C++23 refines concepts with better library integration, making codebases more robust and enabling precise type constraints.
  • Coroutines in C++20 simplify asynchronous programming and are lightweight constructs useful for handling concurrency in high-performance systems.
  • Coroutines utilize keywords like co_await and enable event-driven models for efficient scaling.
  • C++23 enhances library support for coroutines, making them more practical for real-world applications.
  • The std::ranges library in C++20 and C++23 offers modern sequence manipulation, aiding lazy evaluation for better performance.
  • Modules in C++23 improve compilation efficiency by replacing headers, leading to faster builds.
  • C++23 expands constexpr and introduces tools for leveraging multi-core CPUs in performance-critical applications.
  • Expected features in C++26 include static reflection and pattern matching for code optimization and readability.
