Forgot the summary:

I chose libclang because:

* It's a stable API
* It's what's recommend if using other language than C++
* I really, really did not want to use C++. After all, I'm using D, not 
C++ :)

I would say it depends on how much you don't want to use C++. If I were 
you, I would definitely give it a try in Rust.
