The Application, Experience, and Prospects of C++ in Xiaomi Vela

This talk draws on practical experience with Quick Apps in Xiaomi Vela to share lessons learned, insights, and future perspectives on using C++ in Xiaomi Vela development. It focuses on two main points: first, the advantages and characteristics of C++ in design patterns and module abstraction, illustrating effective architecture design methods and techniques through the Quick Apps framework; second, the use of C++ smart pointers in conjunction with asynchronous programming to demonstrate how to write safe and maintainable C++ code. Additional topics include C++ coding styles, interoperability with C, and reflections on C++ and Rust development. Outline: 1. Use of C++ in Xiaomi Vela: versions, compilation, and constraints 2. Construction and destruction of static and global C++ objects in Xiaomi Vela 3. Common design patterns in Xiaomi Vela (Factory, Observer, Mediator, etc.) 4. Simplifying complexity: applying design patterns with Quick Apps package management (2–3 pages) 5. Effective use of smart pointers: techniques for safe C++ development 6. Using C++ shared_ptr with MessageLoop 7. Managing C++ object lifecycles with asynchronous programming: unique_ptr, raw pointers, and weak references 8. Interoperability with C: overlapping encapsulation of C and C++ code 9. Reflections on C++ coding style 10. C++ and Rust: personal perspectives on the future development of C++
