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

When using coroutines in C++20, it's important to manage resources carefully, avoid blocking operations, and ensure proper error handling.

Can you explain how to handle errors in coroutines?

Certainly! You can use try-catch blocks within your coroutine to handle exceptions, and also consider using std::exception_ptr for asynchronous error handling.

What about performance considerations?

Performance can be optimized by minimizing heap allocations, using stackful coroutines when necessary, and avoiding unnecessary context switches.

Are there any common pitfalls to avoid?

Yes, common pitfalls include forgetting to resume coroutines, not managing lifetimes properly, and mixing synchronous and asynchronous code without care.
