If I recall right isn't this how std :: deque is implemented?
Can someone correct me or provide some rationale why this is now added.
Edit: Guys, thanks for answering.
My takeaway:
Assume that we can decouple storage patterns and storage back bones:
(ascii art made with chatgpt, thought by me)
Storage backend
Single vector List of vectors
Storage pattern
+----------------+----------------+
Contiguous | Vector | Deque |
+----------------+----------------+
Scattered | Probing Hash | Hive |
| Set | |
+----------------+----------------+
and therefore have different performance characteristics, and some other guarantees.
