Swap two objects.
void swap( object& other);
Exchanges the contents of this object with another object. Ownership
of the respective memory_resource objects is not
transferred.
*other.storage() == *this->storage(), ownership of the underlying memory
is swapped in constant time, with no possibility of exceptions. All
iterators and references remain valid.
*other.storage() != *this->storage(), the contents are logically swapped
by making copies, which can throw. In this case all iterators and
references are invalidated.
Constant or linear in size()
plus other.size().
Strong guarantee. Calls to memory_resource::allocate
may throw.
