Description
[!NOTE]
The issue description has been rewritten by @fmease.
See its API docs: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_analysis/hir_ty_lowering/index.html.
The chapter should explain:
- Meaning & origin of its current name (HIR ty lowering) and of its previous name (astconv).
- Purpose, incl. bigger picture
- "Conventions", "restrictions", "self imposed rules" (e.g., https://github.com/rust-lang/rust/pull/125819#issuecomment-2142394608).
- "Limitations" (cc arbitrary shorthand projection & inherent associated type debates)
