Efficiently exchange the nodes of the specified `a` object with those of the specified `b` object. This method provides the no‐throw exception‐safety guarantee. The behavior is undefined unless `a.allocator() == b.allocator()`.

Swap both the value, the hasher, the comparator, and the `maxLoadFactor` of the specified `x` object with the value, the hasher, the comparator, and the `maxLoadFactor` of the specified `y` object. Additionally, if `bslstl::AllocatorTraits<ALLOCATOR>::propagate_on_container_swap` is `true`, then exchange the allocator of `x` with that of `y`, and do not modify either allocator otherwise. This method guarantees `O[1]` complexity if `x` and `y` have the same allocator or if the allocators propagate on swap, otherwise this operation will typically pay the cost of two copy constructors, which may in turn throw. If the allocators are the same or propagate, then this method provides the no‐throw exception‐safety guarantee unless the `swap` function of the hasher or comparator throw. Otherwise this method offers only the basic exception safety guarantee.
