Quick Reference
Rust Errors: Result<T,E> for fallible ops, Option<T> for absence. Use ? operator to propagate. thiserror for libraries (typed errors), anyhow for apps (easy context). Never .unwrap() in production. Add context with .context(). Match on Result for handling. impl From for error conversion.
Use When
- Rust application development
- Library development
- Error propagation patterns
- Robust error handling
Skip When
- Non-Rust projects
- Prototyping (unwrap acceptable)
