Rust Developer – 100+ Lab Exercises (Basic, Intermediate, Advanced)

🔰 Basic Level (30+ Exercises)

 

Goal: Build foundational skills in Rust syntax, ownership model, and simple applications.

 

Rust Fundamentals

  • Set up Rust development environment (Rustup, Cargo).

  • Understand Rust syntax: variables, data types, functions.

  • Practice control flow: if, match, loops.

  • Implement basic ownership and borrowing concepts.

  • Work with references and basic lifetimes.

Data Structures & Collections

  • Use Rust primitive data structures (arrays, tuples).

  • Explore vectors, strings, and slices.

  • Practice using hash maps and sets.

  • Implement enums and pattern matching.

Error Handling

  • Learn Result and Option types.

  • Implement basic error handling with unwrap, expect.

  • Create custom error types with enums.

Modules & Crates

  • Organize code using modules and packages.

  • Create and publish a simple crate to crates.io.

 

🚀 Intermediate Level (40+ Exercises)

 

Goal: Master advanced Rust concepts, concurrency, and ecosystem tools.

 

Advanced Ownership & Lifetimes

  • Deep dive into borrowing rules and lifetime annotations.

  • Practice lifetime elision and advanced lifetime scenarios.

Traits & Generics

  • Define and implement custom traits.

  • Use generics in functions, structs, and enums.

  • Understand trait bounds and where clauses.

Concurrency & Async Programming

  • Implement multi-threading with std::thread.

  • Use channels for message passing.

  • Build asynchronous applications using async/await.

  • Work with tokio or async-std runtimes.

Testing & Documentation

  • Write unit and integration tests.

  • Use rustdoc to generate documentation.

  • Practice Test-Driven Development (TDD).

Ecosystem & Tooling

  • Use Cargo features: workspace, profiles, dependencies.

  • Manage versions with semantic versioning.

  • Use clippy and rustfmt for linting and formatting.

 

🧠 Advanced Level (40+ Exercises)

 

Goal: Achieve expertise in systems programming, unsafe Rust, and ecosystem integration.

 

Unsafe Rust & FFI

  • Understand when and how to use unsafe.

  • Work with raw pointers and manual memory management.

  • Interface with C libraries via Foreign Function Interface (FFI).

Macros & Metaprogramming

  • Write declarative macros using macro_rules!.

  • Create procedural macros for custom code generation.

Performance Optimization

  • Profile applications with perf, valgrind, or other tools.

  • Optimize code for performance and memory usage.

Embedded & Systems Programming

  • Develop firmware-level Rust apps (e.g., Raspberry Pi).

  • Work in no_std environments for bare-metal development.

WebAssembly & Networking

  • Compile Rust to WebAssembly and integrate with JavaScript.

  • Build networked applications using hyper, reqwest.

Large-Scale Projects & Ecosystem Contribution

  • Contribute to open-source Rust projects.

  • Architect and manage large Rust codebases.

  • Implement CI/CD pipelines for production-ready Rust apps.
