Basically wrap your data struct in Option<Rc<RefCell<_>>>Better yet, use your custom type that provides few helper functions that make using it as nice as old C++ pointers.Obviously there's no pointer arithmetic, but it works great for dynamically allocated structures like trees or linked lists.Please comment how it's a horrible idea that will bring doom to me and my family. fn main() { struct Data { pub number: i32 } // struct Data { int number; }; let mut p:Pointer<Data> = Pointer(None); // Data *p = NULL; println!("{}", p.is_none()); // printf(p == NULL ? "true\n" : "false\n"); p = Pointer::new(Data { number: 5 }); // p = new Data { number: 5 }; println!("{}", p.pointed().number); // prin
