RA Proc Macro Server This library is able to call compiled Rust custom derive dynamic libraries on arbitrary code. The general idea here is based on . But we adapt it to better fit RA needs: * We use `tt` for proc-macro `TokenStream` server, it is easier to manipulate and interact with RA than `proc-macro2` token stream. * By **copying** the whole rustc `lib_proc_macro` code, we are able to build this with `stable` rustc rather than `unstable`. (Although in general ABI compatibility is still an issue)…
