Summary
This chapter uncovered the integration of C++20’s concepts and coroutines with the STL. We began by exploring the role of concepts in templated programming. Concepts strengthen code robustness by enforcing type constraints and enhancing the expressivity and safety of template use. They replace error-prone SFINAE techniques with a more readable and declarative syntax. We saw how concepts improve the clarity of algorithms’ requirements, leading to more maintainable code.
Next, we examined how coroutines introduce a new level of sophistication to asynchronous programming in C++. We discussed the mechanics of coroutines, emphasizing the use of co_await
, co_return
, and co_yield
for creating nonblocking operations. We looked at how coroutines can interact with STL data structures and algorithms, allowing asynchronous and synchronous code to blend seamlessly.
Understanding the interplay between concepts, coroutines, and the STL is crucial. It enables us to write...
