Rust Learning Roadmap

Stage 1: Foundations

1. Install and update with rustup.
2. Finish Rust Book core chapters: ch02, ch04, ch08, ch09, ch10, ch11.
3. Parallel practice with Rust by Example.

Stage 2: Engineering Core

1. Cargo workflow: new, check, build, test, doc.
2. Error modeling with Result, thiserror-style patterns.
3. Module architecture and workspace split.

Stage 3: Advanced Capabilities

1. Concurrency (std::thread, channels, sync primitives).
2. Async (async/await, runtime model, task cancellation).
3. Unsafe and low-level memory model when necessary.

Stage 4: Production Habits

1. Lint and format by default (cargo clippy, cargo fmt).
2. Structured logs and tracing in services.
3. CI baseline: check + test + clippy + fmt.

Common Pitfalls

• Borrow checker conflicts caused by over-shared mutable state.
• Lifetime errors from returning references with invalid scope.
• Excessive unwrap in non-toy code.
• Async tasks calling blocking operations.
