Instead of cloning, consider using techniques like `Arc>` or channel-based communication to share the error across threads. Another alternative is to send the error over a channel, which transfers ownership (moves) of the error. Using a shared reference wrapped in a mutex allows multiple threads to access the error without cloning and can be useful when the error needs to be mutated. However, this might increase the overhead of error handling.
