Both them are container that give objects interior mutability, which means they are mutable with share reference. Cell provides some api to get or set wrapped value. We can't get a reference from Cell, because we can only get copy value from Cell that guarantee no share reference into wrapped value.
RefCell can get either of share reference or exclusive reference point.
