What are the limitations of C++20 coroutines?

What are the limitations of C++20 coroutines?

C++20 coroutines introduce powerful features, but they have some limitations, such as complexity in error handling and performance overhead.

Can you elaborate on the error handling limitations?

Sure! Error handling in coroutines can be tricky because exceptions thrown in a coroutine may not propagate as expected, leading to potential resource leaks.

Are there any performance concerns with using coroutines?

Yes, while coroutines can improve readability and maintainability, they may introduce performance overhead due to context switching and state management.

How do coroutines compare to traditional threading?

Coroutines are generally lighter than threads, as they don't require separate stacks and can be more efficient for I/O-bound tasks, but they may not utilize multiple cores effectively.

What are some best practices for using coroutines in C++?

Best practices include keeping coroutine logic simple, avoiding heavy computations within coroutines, and ensuring proper cleanup of resources.
