error[E0506]: cannot assign to `*node_ref` because it is borrowed

|
|
LL | fn remove_last_node_iterative<T>(mut node_ref: &mut List<T>) {

LL | loop {

LL | let next_ref = &mut node_ref.as_mut().unwrap().next;

|
| -------- `*node_ref` is borrowed here
|

...

LL | node_ref = next_ref;
|
|
| ------------------- assignment requires that `*node_ref` is borrowed for `'1`

...
|
|
LL | *node_ref = None;
|
|
| ^^^^^^^^^ `*node_ref` is assigned to here but it was already borrowed
