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.
