Detailed Description

template<class t_VARIANT, class t_TYPE, size_t t_INDEX = BSLSTL_VARIANT_CONVERT_INDEX_OF(t_TYPE, t_VARIANT)>
struct bslstl::Variant_isAlternativeAssignableFrom< t_VARIANT, t_TYPE, t_INDEX >

This component-private metafunction is derived from bsl::true_type if there is a unique best match alternative in (template parameter) t_VARIANT for std::declval<t_TYPE>() and that alternative is both constructible and assignable from std::declval<t_TYPE>(), and bsl::false_type otherwise.
