Most of the time, Rust's ownership system is helpful. Sometimes, it's a pain though. In these cases, you can actually work around the ownership system if you need too. For instance, you can use Arc [1] to share memory between threads or Rc [2] to enable thread local GC for a specific variable or RefCell [3] to safely share mutable memory between threads. You can even use raw pointers: it's unsafe (and therefore has to be wrapped in an "unsafe { ... }" block) but possible. Finally, you can call C very easily from Rust [4].
