interior_mutability_pointer 0.1.1

A wrapper around Rc<RefCell<T>> allowing immediate access to inner methods, without the need for .borrow() or .borrow_mut(), allowing for a more seamless pointer experience.

let mut k = Imp::new(String::new());
let p = k.clone(); // Clone the pointer.
k.push_str("yo");
println!("{} {}", k, p); // Prints "yo yo"

Also allows the use of operators:

let mut k = Imp::new(5);
let p = k.clone(); // Clone the pointer.
k += 5;
println!("{} {}", k, p); // Prints "10 10"

The biggest difference to Rc<RefCell<T>> is that your pointer instance will need to be marked as mut if you want to use &mut self methods, as opposed to Rc<RefCell<T>> instances where you can call .borrow_mut(), removing the need for the mut keyword. However, this does not mean that all clones of the pointer need to be mutable!

let k = Imp::new(String::new());
let mut p = k.clone(); // Clone the pointer.
p.push_str("yo");
println!("{:?} {:?}", k, p); // Prints "yo yo"
