Instead this can be ignored in the Gir.toml file which will drop it from the ffi tests

I tried that but couldn't get it to work, let me try again

we do that in gtk for the version constants for example

shouldn't this be fixed upstream?

You can add (type uint) annotation for this IIRC

And (value 4294967292). That's done in GStreamer in many places. It also confuses the Python bindings if you don't do that, but I guess nobody is using G_LOG_LEVEL_MASK from Python.

I think we have this problem with any flags type, we consider them u32 but in C anything in an enum has to be int. Maybe I will just have gir cast them to unsigned

Yeah it looks like those annotations won't work on an enum constant, they only work on a #define

Similar to the other constant

g_macro__has_attribute___noreturn__andG_LOG_DOMAINare used for C macros, should not be in ffi at allG_LOG_LEVEL_MASKis considered unsigned by rust but C defines it as signed
