What you will learn

• Write memory-safe Rust programs without a garbage collector by applying ownership, borrowing, and the `Copy`/`Clone` trait rules

• Handle errors idiomatically with `Option<T>`, `Result<T, E>`, `match`, and the `?` operator — no `null`, no uncaught exceptions

• Build reusable abstractions with generics, traits, and lifetimes, and organize code using modules, closures, and iterators
