pub struct BuildFlags(pub HashSet<BuildFlag>);
Expand description
A list of python interpreter compile-time preprocessor defines.
PyO3 will pick these up and pass to rustc via --cfg=py_sys_config={varname}
;
this allows using them conditional cfg attributes in the .rs files, so
#[cfg(py_sys_config="{varname}")]
is the equivalent of #ifdef {varname}
in C.
see Misc/SpecialBuilds.txt in the python source for what these mean.
