23.6 Container adaptors [container.adaptors]

23.6.1 In general [container.adaptors.general]

The headers <queue> and <stack> define the container adaptors queue, priority_queue, and stack. These container adaptors meet the requirements for sequence containers.

The container adaptors each take a Container template parameter, and each constructor takes a Container reference argument. This container is copied into the Container member of each adaptor. If the container takes an allocator, then a compatible allocator may be passed in to the adaptor's constructor. Otherwise, normal copy or move construction is used for the container argument.

For container adaptors, no swap function throws an exception unless that exception is thrown by the swap of the adaptor's Container or Compare object (if any).
