Because Role
struct contains a Vec, so I can't impl a Copy trait for it.I want to achieve the goals that when modifying role1
, the role1
in h
and role2
get updated.

You're trying to call the into_inner
method from RefCell
, which takes ownership of the refcell and destroys it. However since you're storing it in an Rc
, you cannot take it out, since there might be several Rc
-pointers to that same RefCell
, and destroying it would invalidate the others.
Here Playground every vec's role1 is updated. Here is a good explanation of using Rc<RefCell<T>>
Why this code doesn't panic? ignore the title.
Interesting, Your code and my code are almost the same, the only difference is I created a new variable named new_role1
while yours not. I will try this, thanks.
With your help here I think I can solve Role inheritance problem in rbac.rs · Issue #7 · casbin/casbin-rs · GitHub this issue today.
