//! HIR (previously known as descriptors) provides a high-level object oriented
//! access to Rust code.
//!
//! The principal difference between HIR and syntax trees is that HIR is bound
//! to a particular crate instance. That is, it has cfg flags and features
//! applied. So, the relation between syntax and HIR is many-to-one.
