If the specified `rhs` holds the same alternative type as this object, move assign the contained value of `rhs` to the contained value of this object. Otherwise, destroy the currently held alternative object (if any) and, if `rhs` holds a value, move‐construct the corresponding alternative of this object from the contained value of `rhs`. The allocators of this object and `rhs` both remain unchanged. If the construction of a new alternative object exits via an exception, this `Variant_Base` object is left in a valueless by exception state. All alternatives shall be move constructible and move assignable.
