1//! Rustc proc-macro server implementation with ra_tt
2//!
3//! Based on idea from https://github.com/fedochet/rust-proc-macro-expander
4//! The lib-proc-macro server backend is `TokenStream`-agnostic, such that
5//! we could provide any TokenStream implementation.
6//! The original idea from fedochet is using proc-macro2 as backend,
7//! we use ra_tt instead for better intergation with RA.
8//!
