What are the best practices for using C++20 coroutines?

What are the best practices for using C++20 coroutines?

When using C++20 coroutines, it's important to keep your code readable and maintainable. Use clear naming conventions for coroutine functions and avoid deep nesting of coroutines.

Can you explain how to handle errors in coroutines?

Certainly! You can handle errors in coroutines by using try-catch blocks within the coroutine. Additionally, consider using a custom awaitable type that can propagate errors.

What are some common pitfalls to avoid?

Common pitfalls include not properly managing the lifetime of coroutine objects and misunderstanding the suspension and resumption of coroutines. Always ensure that resources are released appropriately.

How do coroutines compare to traditional threading?

Coroutines are generally lighter than threads, as they allow for asynchronous programming without the overhead of thread management. They can improve performance in I/O-bound applications.

Any tips for debugging coroutines?

Use logging extensively to trace coroutine execution. Tools like std::coroutine_handle can help inspect the state of coroutines during debugging.
