pub static mut NODE_RC_MAX_GUARD: usize👎Deprecated:
no longer used; node_ptr_mut now relies on RefCell::try_borrow_mut
Expand description
Deprecated, unused. Formerly the Rc::strong_count threshold consulted by
Node::node_ptr_mut. That heuristic was replaced by a
RefCell::try_borrow_mut check (a high clone count is not an aliasing
conflict), so this value is no longer read. Retained only for API
compatibility.
