error[E0373]: closure may outlive the current function, but it borrows `inner`, which is owned by the current function
--> $DIR/scope_callback_inner.rs:8:34

5 | lua.scope(|scope| {

...
8 | .create_function_mut(|_, t: Table| {
| ^^^^^^^^^^^^^ may outlive borrowed value `inner`
9 | inner = Some(t);

note: function requires argument type to outlive `'2`

help: to force the closure to take ownership of `inner` (and any other referenced variables), use the `move` keyword

8 | .create_function_mut(move |_, t: Table| {
| ^^^^^^^^^^^^^^^^^^
