Refactor `rustc_attr_data_structures` documentation by xizheyin · Pull Request #142082 · rust-lang/rust

xizheyin · 2025-06-05T14:10:07Z

I was reading through AttributeKind and realized that attributes like InlineAttr didn't appear in it, however, I found them in rustc_codegen_ssa and understood why (guessing).

There's almost no overall documentation for this crate, I've added the organized documentation at the top of lib.rs, and I've grouped the Attributes into two categories: AttributeKind that run all through the compiler, and the ones that are only used in codegen_ssa, such as InlineAttr, OptimizeAttr, InstructionSetAttr.

Also, I've added documentation for AttributeKind that further explains why attributes like InlineAttr don't appear in it, with examples for each variant.

As per my previous comments, won't approve this PR for the time being despite it having some good changes.

I also remove the comments in variants of AttributeKind.

likely to conflict (minorly) with #138164, let's wait for that to merge (or preemptively rebase ontop of it). It's in the queue, judging by the state of which it'll take an hour or 8 for that to get through. Will look again tonight (european time)

Seems to not conflict with #138164, let me rebase it.

+//! Data structures for representing parsed attributes in the Rust compiler.
+//! For detailed documentation about attribute processing,

I remove all of other docs.
