Class result_union<T, E, IsTrivial>

/////////////////////////////////////////////////////////////////////////// /// \brief A basic utility that acts as a union containing the T and E /// types /// /// This is specialized on the case that both T and E are trivial, in which /// case result_union is also trivial /// /// \tparam T the value type result to be returned /// \tparam E the error type returned on failure /// \tparam IsTrivial Whether or not both T and E are trivial ///////////////////////////////////////////////////////////////////////////
