Detailed Description

The main use of this tag is to allow fetching the DataBox from itself. The primary use case is to allow an invokable to take a DataBox as an argument when called through db::apply.

  auto check_result_no_args = [](const decltype(original_box)& box) {
    CHECK(db::get<test_databox_tags::Tag2>(box) == "My Sample String"s);
    CHECK(db::get<test_databox_tags::Tag5>(box) == "My Sample String6.28"s);
  };
  db::apply<tmpl::list<Tags::DataBox>>(check_result_no_args, original_box);
