M03 Mutability
zhanghandong/rust-skillsRust's borrow checker enforces strict rules about who can change data. When you see errors like E0596 or E0502, it means you have a mutability conflict. This skill helps you understand why the data needs to change and who can change it.
You will learn about interior mutability with types like Cell and RefCell. For thread-safe code, you use Mutex and RwLock. The skill shows you how to choose the right pattern for your situation.
Instead of quickly adding 'mut', you stop and ask better questions. This leads to cleaner, safer Rust code. Developers at any level can benefit from these clear guidelines.
