Rust Best Practices

Ownership & Borrowing

• Prefer borrowing over ownership transfer
• Use &str for function parameters over String
• Clone only when necessary
• Use Cow for maybe-owned strings

Error Handling

• Use Result<T, E> for recoverable errors
• Use panic! only for unrecoverable errors
• Use ? operator for error propagation
• Create custom error types with thiserror
• Use anyhow for application errors
