What are the best practices for error propagation in Rust?

In Rust, it's essential to use the Result and Option types for error handling. This allows you to propagate errors effectively.

Can you explain how to use the ? operator for error propagation?

Sure! The ? operator can be used to simplify error handling. It automatically returns an error if the result is an Err, allowing for cleaner code.

What should I do if I need to handle multiple errors?

You can use the ? operator in combination with Result types. Alternatively, consider using the anyhow crate for more complex error handling.

Are there any common pitfalls to avoid?

Yes, avoid using unwrap() or expect() in production code, as they can cause panics. Always handle errors gracefully.
