WritableDequeIterator

pub final class WritableDequeIterator<T>

Traverses borrowed circular storage as writable element references.

The cursor allocates nothing and retains no owner. Next costs O(1); exhaustion is permanent. Any structural owner mutation, move or destruction invalidates the cursor and yielded references. External synchronization is required. T: Exact ring element type.

WritableDequeIterator.Next

pub fn Next() -> mut T&?

Advances and borrows the next logical ring element. Return: Optional writable reference, or none after exhaustion. Warning: References never retain storage; owner invalidation rules apply.
