/*
** This file contains definitions of structs that should be considered private
** and NOT stable across versions of upb.
**
** The only reason they are declared here and not in .c files is to allow upb
** and the application (if desired) to embed statically-initialized instances
** of structures like defs.
**
** If you include this file, all guarantees of ABI compatibility go out the
** window! Any code that includes this file needs to recompile against the
** exact same version of upb that they are linking against.
**
** You also need to recompile if you change the value of the UPB_DEBUG_REFS
** flag.
