[$] Analyzing Rust programs with Charon

Nadrieril is a long-time Rust contributor, and the maintainer of the rustc pattern-matching infrastructure.

During his involvement with Rust, he has noticed a problem with the usability of the language: it is difficult to automatically extract information from a Rust crate for use with other tooling.

The Charon project aims to fix that by providing a stable API for accessing internal information from the Rust compiler.
