Copy‐assign to the active alternative of *d_variant_p from the specified value (i.e. the alternative that is being visited). The behavior is undefined unless (template parameter) t_INDEX is the index of the active alternative of *d_variant_p (or, in C++03, the index of an alternative that has the same type as the active alternative).
