Seems fine to me; just make sure to use exhaustive matching where appropriate by enumerating the fields with |

Not sure what "of" signifies here. I would rename this to trait_ref and let the type system speak to the Option<_>

It's Some if the item is an impl of a trait.

But what does the f stand for? (I know what the field means.)

"of" like the preposition. An impl of a trait.

Oh. Well that was far from obvious. :) Given that you had to ELI5 it for me, could we change it to something else?

I could, although to be honest I'm not enthusiastic about it. On a personal note, I have less time to contribute to open source this year, and having to spend some of it arguing over trivial choices like this has left me feeling a bit bummed out 😢.
edit: I'm aware that "arguing" requires two parties, so I'm partly responsible for using my time this way. I suppose I just don't see the value in this kind of extremely granular review.

(Fwiw, I didn't think we were arguing -- I was just confused as to what it signified.)

Use named fields for `{ast,hir}::ItemKind::Impl`
Currently, the widely used `ItemKind::Impl` variant is a tuple with seven fields. I want to add an eighth in rust-lang#68140, which means I have to update most matches on this variant anyways. Giving a name to each field improves readability and makes future changes of this nature much simpler.
This change will cause several tools to break. I will fix them once this is merged.
