55 // A dummy enum that, when passed as argument to a consteval constructor, will
56 // mean that we want this constructor to be used to initialize a static variable
57 // at compile time.
58 // Basically, the idea is the following:
59 // 1/ in the .cpp file, create the "constinit const" static variables you need
60 // using a constructor to which StaticInitializer::CONSTINIT is passed in
61 // argument (see file tools/core/AVLTree.cpp)
62 // 2/ in the .h file, declare "extern constinit cont" these static variables.
63 // If these correspond to iterators of templates, you may need to declare
64 // pointers to these variables as "inline constexpr void* const" and use
65 // these pointer rather than the static variables themselves (this avoids
66 // having a lot of strict-aliasing rule warnings). See the very end of
67 // file AVLTree.h for an example.
