libusearch - microlib for searching/graph traversal

This library provides a minimalistic implementation of the A* algorithm,
following the structure and naming of the related wikipedia article
(to save on the documentation):

https://en.wikipedia.org/w/index.php?title=A*_search_algorithm&oldid=986803280


There are two ways to compile the lib with your project:

1. as inline functions (to save a few calls):

    #define USRCH_INLINE static inline
    #include <libusearch/a_star_api.h>
    #include <libusearch/a_star_impl.h>

   No linking needed.

2. as a static library:

    #include <libusearch/a_star_api.h>

   And then link to libusearch.a


API documentation: commends in a_star_api.h.

Example: tester.c
