> Getters return values. This returns a pointer. So it's an accessor. With unchecked semantics. This isn't exactly a pointer: Rust distinguishes between read-only and mutable ("exclusive") references. This returns a read-only reference, so it's very much like a getter: you cannot use it to modify the thing it points to. It's just that it does it without a copy, which matters for performance in some cases.
