# RcCell
A convenient wrapper for `Rc<RefCell<T>>>` and `Weak<RefCell<T>>>`.
The `RcCell` library adds two new structs:
- `RcCell<T>`: a wrapper for `Rc<RefCell<T>>`.
- `WeakCell<T>`: a wrapper for `Weak<RefCell<T>>`.
This library extends the [`rc-cell`](https://crates.io/crates/rc-cell) library.
## Example
```rust
use rccell::{RcCell, WeakCell};
let a = RcCell::new(1); // a is a RcCell that wraps an Rc<RefCell<i32>>
let b = a.clone(); // You can create multiple RcCells pointing to the same data.
let mut c = a.borrow_mut(); // You can use borrow and borrow_mut methods as if RcCells were RefCells
*c = 2;
// let mut d = b.borrow_mut() You cannot create two RefMuts for the same RcCell.
drop(c);
assert!(a.try_borrow().is_ok()); // You can use try_borrow and try_borrow_mut to avoid panicking
// let d = a.unwrap() You can use unwrap to get the inner value (if there is only one RcCell)
assert!(a.try_unwrap().is_err()); // You can use try_unwrap to avoid panicking
let d: WeakCell<i32> = b.downgrade(); // Use downgrade to create a WeakCell pointing to the same data
assert!(d.upgrade().is_some()); // Use the upgrade method to get a RcCell pointing to the same data as the WeakCell.
