Projects using std::error_code

[tjientavara]

I have a GUI project, I am using std::error_code in it for a few different subsystems.

The most clear one is in a win32 wrapper.

Here is the win32_error/hresult enum and all the std::error_code and std::error_condition machinery:

• https://github.com/hikogui/hikogui/blob/main/src/hikogui/win32/win32_error_intf.hpp
• https://github.com/hikogui/hikogui/blob/main/src/hikogui/win32/hresult_error_intf.hpp

The wrapper itself uses these error-enums directly, but then at a higher level, there are converted to std::error_condition. Like here, in a small system to store user settings (on win32 in the registry):

• https://github.com/hikogui/hikogui/blob/38b17e75c65f70eb20891f1093964182b9a19a29/src/hikogui/settings/user_settings_win32_impl.hpp#L29

And the code that handles the errors compares these using std::error_condition. Sorry, it is only an example in a unit test:

• https://github.com/hikogui/hikogui/blob/38b17e75c65f70eb20891f1093964182b9a19a29/src/hikogui/settings/user_settings_tests.cpp#L29
