Assignment operators

== Synopses

Declared in `<bslstl_variant.h>`

If the specified `rhs` holds the same alternative type as this object, copy assign the contained value of `rhs` to the contained value of this object. Otherwise, destroy the contained value of this object (if any) and, if `rhs` holds a value, copy‐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. This behavior differs from the standard, for reasons that are explained in the documentation for `variant::operator=`. All alternatives shall be copy constructible and copy assignable.

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.
