Users create instances using the StreamOf<T>(range) non-member factory function (defined below). The following is a typical usage of this class in a range-for loop.
auto row_range =... usingRowType= std::tuple<std::int64_t, std::string,bool>; for(autoconst& row :StreamOf<RowType>(row_range)){ if(!row){ // Handle error; } std::int64_t x = std::get<0>(*row); ... }
