The HIR – "High-Level Intermediate Representation" – is the primary IR used in The HIR – "High-Level Intermediate Representation" – is the primary IR used in
most of rustc. It is a compiler-friendly representation of the abstract syntax most of rustc. It is a compiler-friendly representation of the abstract syntax

resolution. Many parts of HIR resemble Rust surface syntax quite closely, with resolution (see [Lowering](./lowering.md) for how the HIR is created).

This makes HIR more amenable to analysis than a normal AST. This makes HIR more amenable to analysis than a normal AST.
