Rust collections include **lists** (`LinkedList`), **vectors** (`Vec`) for dynamic arrays, and **hash maps** (`HashMap`) for key-value pairs. `Vec` is the most common, offering dynamic resizing. Collections provide iterators, robust error handling, and memory safety, enabling efficient data management. Use the `std::collections` module for advanced collections.
