HashMapIterator

pub final class HashMapIterator<K, V> where K: Movable where V: Movable

Scans borrowed map buckets as readonly entry views.

Full traversal costs O(capacity), skipping empty/deleted slots without allocation. Bucket order is unspecified. Exhaustion is permanent. The cursor retains no owner; structural mutation, move/destruction invalidate it and yielded views. K: Movable stored key type, always borrowed readonly. V: Movable stored value type.

HashMapIterator.Next

pub fn Next() -> HashMapEntryView<K, V>?

Scans to the next occupied bucket and borrows its entry. Return: Optional entry view, or none permanently after all buckets are scanned. Warning: Next can scan O(capacity) absent buckets; owner invalidation rules apply.
