* Include this header if you need the id types and not the whole Box2D API.
* All ids are considered null if initialized to zero.
*
* For example in C++:
* For example in Odin:
*
* @code{.cxx}
* b2WorldId worldId = {};
* @code{.odin}
* worldId := b2.WorldId{}
* @endcode
*
* Or in C:
*
* @code{.c}
* b2WorldId worldId = {0};
* @endcode
*
* These are both considered null.
* This is considered null.
*
* @warning Do not use the internals of these ids. They are subject to change. Ids should be treated as opaque objects.
* @warning You should use ids to access objects in Box2D. Do not access files within the src folder. Such usage is unsupported.
