Conquering Rust: Practical Tips to Avoid Common Pitfalls

2025-05-13

This article summarizes common mistakes Rust learners make and offers practical advice. The core is shifting your mindset: treat the compiler as a collaborator, not an adversary, and actively use its error messages to learn. The author suggests starting with simple examples, gradually increasing complexity, and mastering core concepts like ownership and lifetimes. Furthermore, the article emphasizes attention to detail, reading standard library documentation, and improving skills through practice and code reviews.

Gracefully Handling Option in Rust: Beyond unwrap()

2025-05-13

Handling the `None` variant of `Option` in Rust is a common pain point. This article explores safer alternatives to `unwrap()`, focusing on robust `None` handling. It starts by dissecting the compilation error from using the `?` operator directly and the runtime risks of `unwrap()`. Then, it details three approaches: `ok_or()`, `match` statements, and the `let-else` expression (introduced in Rust 1.65), comparing their pros and cons. `let-else` emerges as the recommended best practice due to its conciseness, readability, and maintainability, leading to more robust and understandable code.

Rust's Safety Traps: Even Safe Rust Isn't Foolproof

2025-04-06

This article unveils common pitfalls in safe Rust code that the compiler misses. It covers integer overflows, type casting errors, array out-of-bounds issues, invalid states, sensitive data exposure, and more, providing solutions like checked arithmetic, TryFrom, the `get` method, and custom types. The author emphasizes that even with Rust's memory safety guarantees, developers need discipline, combining testing, linting, and fuzzing to build robust applications.

Rust Prototyping: Debunking the Myths

2025-01-17

This article challenges the common belief that Rust is unsuitable for rapid prototyping. The author argues that Rust's strong type system and tooling actually help developers catch design flaws early, reducing rework later. The article details several Rust prototyping techniques, such as using simple types, leveraging type inference, judiciously using `unwrap`, and utilizing IDE features effectively. Real-world examples illustrate how Rust's type system aids design, leading to robust production-ready code. The author also emphasizes avoiding premature optimization and recommends the `dbg!` macro for debugging. In short, this article provides a practical guide to Rust prototyping, enabling developers to efficiently translate ideas into working code.
