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 = ...
using RowType = std::tuple<std::int64_t, std::string, bool>;
for (auto const& row : StreamOf<RowType>(row_range)) {
if (!row) {
// Handle error;
}
std::int64_t x = std::get<0>(*row);
...
}
