What are the best practices for writing functions in Rust?

When writing functions in Rust, consider the following best practices: keep functions small, use clear naming conventions, and leverage Rust's ownership model.

Can you explain why keeping functions small is important?

Keeping functions small enhances readability and maintainability. It allows for easier testing and debugging.

What naming conventions should I follow?

Use snake_case for function names and be descriptive. For example, calculate_area is better than calc.

How does Rust's ownership model affect function design?

Rust's ownership model ensures memory safety without a garbage collector, so design functions to take ownership, borrow, or return values appropriately.

Any tips for error handling in functions?

Use the Result type for functions that can fail, and consider using the ? operator for concise error propagation.
