The nlohmann.json module includes json_view.hpp in its global module fragment and exports basic_json_document, basic_json_view, and the four aliases next to basic_json, json, and ordered_json. features/modules.md lists them, and tests/module_cpp20 parses a document, so that a missing export fails the ci_module_cpp20 job.

// GCC workaround for C++ modules support.
|
|
// When using C++20 modules, some compilers (particularly GCC) may have issues
|
|
// with template instantiations in the module preamble. If you encounter
|
|
// "redefinition" errors when including nlohmann/json.hpp, try one of:
|
|
// 1. Include nlohmann/json.hpp in your module preamble BEFORE other #includes
|
|
// 2. Or use: import nlohmann.json; instead of #include <nlohmann/json.hpp>
|
|
// 3. Or upgrade to a newer GCC version with better modules support.
|
|
// See: https://github.com/nlohmann/json/issues/5103
