HashSetIterator

pub final class HashSetIterator<K> where K: Movable

Borrows set keys readonly in unspecified bucket order.

Full traversal costs O(capacity), allocates nothing and skips deleted/empty buckets. Exhaustion is permanent. The cursor retains no owner; structural mutation, move/destruction invalidate it and yielded key references. K: Movable stored key type, always yielded readonly.

HashSetIterator.Next

pub fn Next() -> K&?

Advances once and borrows the next stored key readonly. Return: Optional readonly key reference, or none permanently after exhaustion. Warning: May scan absent buckets; owner invalidation rules apply.
