Rust Programming Language Fundamentals Practice

**Rust** is a systems programming language that prioritizes memory safety without sacrificing performance. This exam focuses on essential language features used in real projects. Topics include: ownership and moves, borrowing with references, lifetimes, and rules that ensure safe memory management; mutability and interior mutability; generics and trait bounds; traits and trait objects for abstraction; pattern matching, enums, and error handling; crates and modules, visibility, and crate types; cargo workflows, dependencies, and building projects; concurrency primitives, Send and Sync, and fearless concurrency; async/await basics and futures; and common compiler errors with meaningful error messages. Questions blend theoretical principles with practical syntax to evaluate understanding and apply concepts correctly. The exam is designed for IT students and professionals pursuing Rust knowledge; it emphasizes safety, bite-sized reasoning, and the ability to reason about ownership without a garbage collector. Practicing with these MCQs helps reinforce correct mental models, improves recall, and builds confidence for hands-on coding. The structure mirrors typical IT certification formats, with clear stems, distractors, and concise explanations. By completing the set, learners gain familiarity with the language's philosophy, such as zero-cost abstractions, type inference, and expressive enums. Regular practice strengthens diagnostic skills, reduces debugging time, and supports writing robust, maintainable Rust software. This resource serves as a practical bridge between theory and implementation for developers entering system programming, web services, or embedded domains where Rust shines.
