Struct Cursor

Source 
struct Cursor<'l, T>(MutexGuard<'l, *mut Node<T>>);
Expand description

Reference to the next field of previous node which points to the current node.

For example, given the following linked list:

head -> 1 -> 2 -> 3 -> null

If cursor is currently at node 2, then cursor.0 should be the MutexGuard obtained from the next of node 1. In particular, cursor.0.as_ref().unwrap() creates a shared reference to node 2.

Tuple Fields§
