Rust Error Handling - Best Practices

Here are some best practices for error handling in Rust programming that I've found effective: For tests and examples, use "box dyn error" instead of "anyhow." Prefer the "?" pattern over "unwrap" or "expect," even in tests and examples, to align with production coding standards. "Box dyn error" is excellent for error passthrough, as are `map_err` and `ok_or` with static strings and formatted strings. In production code, use an enum with fully descriptive variant names and favor struct variants with clear names over tuple variants. Avoid relying on the display to convey the meaning of error variants. In web or device applications, human error rendering might not occur at the enum/type level, so using Debug for display may suffice. For web or device applications, using Serialize for errors that need to be logged or sent to the client for display can be a powerful and straightforward pattern. Prioritize clarity in error naming (variants) and focus on consistency as the code develops. Don't be afraid of medium-length enum variant names; remember, type refactoring is straightforward. In summary, start with progressive and clear practices, and become more structured as the code matures. == Jeremy Chone: Patreon -   / jeremychone   - Any help is a big help (for Rust educational content) Twitter -   / jeremychone   Discord general-rust -   / discord   Discord rust10x -   / discord   Rust10x - https://rust10x.com - Rust resources for production coding.
