Expand description

A double-ended queue (deque) implemented with a growable ring buffer.

This queue has O(1) amortized inserts and removals from both ends of the container. It also has O(1) indexing like a vector. The contained elements are not required to be copyable, and the queue will be sendable if the contained type is sendable.
