Next Steps

What you can do now

• Install Rust with rustup and use Cargo
• Explain ownership, moves, and borrowing
• Use structs, enums, Option, Result, and Vec
• Organize modules, add a crate, and run tests

Practice ideas

Build a command-line to-do list that stores items in a file using Result and ?. Cover parsing with unit tests.

Common traps

• Fighting the borrow checker instead of restructuring data
• Overusing unwrap
• Indexing strings by bytes unsafely
• Growing main instead of modules and functions

Where to go next

• Lifetimes in more depth
• Iterators and closures
• Async Rust with tokio
• Error crates like thiserror and anyhow
• Clippy lints and rustfmt for style
