  A few example on how to pass data between rust and C

There are plenty of materials online devoted to building the C code and linking it to the rust crate using build.rs file, however I significantly fewer articles about adding rust code to the C project. In contrast, I would like to implement the main function of my example project in C language and use CMake as the build system. I would the CMake project to use the rust crate as a library and generate C header files based on the rust code. The source code of the complete project is in github.

The easiest way to obtain the headers for the rust code is to use the cbingen library.
