think what I've learned this morning is that RefCell is for mutating inside short-lived borrows, whereas I'm attempting to extract long-lived references from something, intertwined with mutating it, which is never going to work

I've always thought that refcell was more for temporarily extracting mutable references from behind shared references and applying runtime borrow rules to those temporary inner borrows which sounds like what you're trying to do...

Actually I guess that's exactly cells responsibility. I really don't understand refcell I think...

Cell is T and RefCell is &T

Cell lets you mutate a non-mutable T, and RefCell lets you mutate a non-mutable &T

They both own the data though right? And they both allow getting &mut T from an &.*Cell<T> right?

Cell does not have anything that is `fn(&self) -> &mut T`. It does have a `fn(&mut self) -> &mut T`, but that's not useful for interior mutability.
