syntax: cleanup param, method, and misc parsing by Centril · Pull Request #64910 · rust-lang/rust

Centril · 2019-09-30T02:39:35Z

Do some misc cleanup of the parser:

Method and parameter parsing is refactored.
A parser for const | mut is introduced that Add a raw "address of" operator #64588 can reuse.
Some other misc parsing.

Next up in a different PR:

~~Implementing Diagnostics: help text for missing left-hand side in arbitrary self type #64252.~~ -- maybe some other time...
Heavily restructuring up item.rs which is a mess (hopefully, no promises ^^).

@Centril
Please, merge parse_self_param back into a single function.
Fragmenting implementation like this is harmful for readability.
I may be biased because I wrote it, but from my point of view it's written exactly like it should be (except for moving ifs on arms perhaps).

petrochenkov · 2019-09-30T13:08:04Z

I think the end goal here is unified syntax and AST representation for free, trait, impl and foreign items (#48137) with inappropriate qualifiers or selfs, missing bodies, etc reported as semantic errors.

petrochenkov · 2019-09-30T13:30:29Z

merge ... back into a single function

Same applies to parse_visibility, except perhaps for the diagnostics/recovery-only part.

petrochenkov · 2019-09-30T13:39:38Z

Otherwise, LGTM.
