1 | //! RA Proc Macro Server | ||
2 | //! | ||
3 | //! This library is able to call compiled Rust custom derive dynamic libraries on arbitrary code. | ||
4 | //! The general idea here is based on https://github.com/fedochet/rust-proc-macro-expander. | ||
5 | //! | ||
6 | //! But we change some several design for fitting RA needs: | ||
7 | //! | ||
8 | //! * We use `ra_tt` for proc-macro `TokenStream` server, it is easy to manipute and interact with | ||
9 | //! RA then proc-macro2 token stream. | ||
10 | //! * By **copying** the whole rustc `lib_proc_macro` code, we are able to build this with `stable` | ||
11 | //! rustc rather than `unstable`. (Although in gerenal ABI compatibility is still an issue) | ||
