Here's a quick rundown of Rust's pointer types:

| Type | Name | Summary |
|--------------|---------------------|-------------------------------------------|
| `&T` | Reference | Allows one or more references to read `T` |
| `&mut T` | Mutable Reference | Allows a single reference to |
| | | read and write `T` |
| `Box<T>` | Box | Heap allocated `T` with a single owner |
| | | that may read and write `T`. |
| `Rc<T>` | "arr cee" pointer | Heap allocated `T` with many readers |
| `Arc<T>` | Arc pointer | Same as above, but safe sharing across |
| | | threads |
| `*const T` | Raw pointer | Unsafe read access to `T` |
| `*mut T` | Mutable raw pointer | Unsafe read and write access to `T` |
