//! An experimental implementation of [Rust RFC#2256 libsyntax2.0][rfc#2256].
//!
//! The intent is to be an IDE-ready parser, i.e. one that offers
//!
//! - easy and fast incremental re-parsing,
//! - graceful handling of errors, and
//! - maintains all information in the source file.
//!
//! For more information, see [the RFC][rfc#2265], or [the working draft][RFC.md].
//!
//!   [rfc#2256]: <https://github.com/rust-lang/rfcs/pull/2256>
//!   [RFC.md]: <https://github.com/matklad/libsyntax2/blob/master/docs/RFC.md>
