It doesn't. There is a type called Gc that may be garbage collected in future, but at the moment it is just a bad reference counted pointer (the Rc type is better if you want reference counting). And it's not even guaranteed that a GC will ever be implemented, Rust provides other abstractions so GC would be rarely used even if it was implemented.
