commit c3d91ae1e87f8a8b8d6b0e7ecd4b7fc09837d30e
Author: Oswald Buddenhagen <o...@users.sf.net>
Date: Thu Dec 17 15:53:40 2020 +0100
introduce new inheritance model based on C11 anonymous structs
the struct declarations got uglier, but their usage requires a lot fewer
explicit references to the parent struct (though some are added where
using the derived struct is more practical now).
we also use something i'd term "covariant members": derivatives of
store_t also reference derivatives of store_conf_t, etc., which
drastically cuts down the number of casts.
fwiw, to achieve this with "proper" inheritance in C++, we'd use
covariant getter functions which hide the still existing casts.
C11 is almost a decade old now, and compilers supported that feature
even longer than that, so i don't expect this to be a problem.
