This code is the MAVLink  protocol handler, and generated by one of the MAVLink specification. It is  C/Rust  mixed project, so to compile it you will need  Rust ,  CC  an any  C  compiler.

To check how slow  rustc  is, check this out , and run  cargo test  in the  GroundControl/demo  dir

Exactly this project is compiled with error, cause the borrow checker complains in one place.

But anyway, the problem is that compilation is unacceptably slow.

Description

/GroundControl/lib   generated API

/GroundControl/demo/src/use_case  is generated sample of using generated API

/GroundControl/demo/src/test  the test

I generate variation of this project, with same functionality, in C, C++, C#.... They are the compiled in seconds !

What wrong with my Rust project? How can I speed up compilation?
