Rust Interview: 200 Questions and Answers

The book "Rust Interview: 200 Questions and Answers" is a practical guide for developers preparing for technical interviews for Rust developer positions. Unlike classic textbooks, this book is focused exclusively on the questions most frequently asked in interviews at leading IT companies that use Rust.

The material is structured into thematic blocks, allowing you to sequentially master all key concepts of the language. Each question is accompanied by a detailed, comprehensive answer with code examples and explanations.

What you will find in the book:

• Basic Syntax and Data Types — variables, primitives, strings, tuples, structs, enums, pattern matching (match).
• Ownership System — ownership rules, borrowing, references, slices, lifetimes.
• Generics & Traits — generic types, traits, dispatch, trait objects, associated types.
• Memory Management — Box, Rc, Arc, RefCell, Mutex, smart pointers, memory leaks.
• Multithreading and Concurrency — threads, channels, mutexes, Send and Sync, async/await, tokio.
• Error Handling — Result, Option, unwrap, expect, the ? operator, custom error types.
• Unsafe Rust — raw pointers, FFI, calling C code, unsafe traits.
• Systems Programming — memory management, allocators, embedded systems, no_std.
• Testing and Debugging — unit tests, integration tests, benchmarks, documentation.
• Architectural Questions — design patterns, Rust idioms, comparison with C++ and Go.

Who this book is for:

• Beginner Rust developers preparing for their first interview.
• Experienced C++/Python/Java programmers transitioning to Rust.
• Tech leads looking to systematize their knowledge.
• Students studying systems programming.

The book does not require deep prior experience with Rust — a basic understanding of programming concepts is sufficient. Each answer is written so that it can be used as a cheat sheet before an interview and as a reference during work.

The "question-answer" format allows you to quickly find the desired topic, and the code examples allow you to immediately apply the knowledge in practice. The author paid special attention to explaining "pitfalls" and typical mistakes that are identified during interviews.

After reading the book, you will confidently answer questions about the borrow checker, lifetimes, concurrency, and memory management — topics that usually cause the most difficulty for candidates.
