utilization.rs

1/// Node utilization of the underlying storage of the self referential collection.
2///
3/// The result contains the following bits of information:
4/// * `capacity`: number of positions that is already allocated.
5/// * `num_active_nodes`: number of active nodes holding data.
6/// * `num_closed_nodes`: number of nodes which had been opened and closed afterwards; however, not yet reclaimed.
7///
8/// Note that `num_active_nodes + num_closed_nodes` reflects the length of the underlying pinned vector,
9/// which is less than or equal to the `capacity`.
