Doubly linked, cyclic list in standard library

问题

I need doubly linked cyclic list, but a cant find it in STL containers (singly linked cyclic list too).

It may looks like that:

element 0   <->   element 1  <-> ... <-> ...

    ^                                     ^
    |                                     |
    v                                     v

element n   <->   element n-1   <->   element n-2

Can you show me what i missed? Thanks in advance.

You haven't missed anything. There is no such container in the standard library.
