How to use it ?

[mschnell1]

I just started checking out this crate.
I managed to compile a testing project that simply calls "decoder".
I suppose the rust files all are compiled, but unfortunately I then get a linker error, so I can't do any tests.
I in fact don't understand how the import of the many .c and .h files that came with the git clone are imported .
Is there any documentation on how to use the crate ?
In the end I want to use it in an embedded project, but right now I simply work on a PC (VSCode on Windows).
Maybe I somehow need to install an appropriate C compiler for creating LLVM from the C files ?
any help ?
Thanks,
