Set the target of this object to the target (if any) held by the specified `rhs` object, destroy the target (if any) previously held by `*this`, and return `*this`. The result is equivalent to having constructed `*this` from `rhs` using the extended move constructor with allocator `this‐>get_allocator()`. If an exception is thrown, `rhs` will have a valid but unspecified value and `*this` will not be modified. Note that an exception will never be thrown if `get_allocator() == rhs.get_allocator()`.
