"Missing" patterns are possible in bare fn types (`fn f(u32)`) and
similar places. Currently these are represented in the AST with
`ast::PatKind::Ident` with no `by_ref`, no `mut`, an empty ident, and no
sub-pattern. This flows through to `{hir,thir}::PatKind::Binding` for
HIR and THIR.
This is a bit nasty. It's very non-obvious, and easy to forget to check
for the exceptional empty identifier case.
This commit adds a new variant, `PatKind::Missing`, to do it properly.
The process I followed:
- Add a `Missing` variant to `{ast,hir,thir}::PatKind`.
- Chang `parse_param_general` to produce `ast::PatKind::Missing`
instead of `ast::PatKind::Missing`.
- Look through `kw::Empty` occurrences to find functions where an
existing empty ident check needs replacing with a `PatKind::Missing`
check: `print_param`, `check_trait_item`, `is_named_param`.
- Add a `PatKind::Missing => unreachable!(),` arm to every exhaustive
match identified by the compiler.
- Find which arms are actually reachable by running the test suite,
changing them to something appropriate, usually by looking at what
would happen to a `PatKind::Ident`/`PatKind::Binding` with no ref, no
`mut`, an empty ident, and no subpattern.
Quite a few of the `unreachable!()` arms were never reached. This makes
sense because `PatKind::Missing` can't happen in every pattern, only
in places like bare fn tys and trait fn decls.
I also tried an alternative approach: modifying `ast::Param::pat` to
hold an `Option<P<Pat>>` instead of a `P<Pat>`, but that quickly turned
into a very large and painful change. Adding `PatKind::Missing` is much
easier.
In the AST, currently we use `BinOpKind` within `ExprKind::AssignOp` and `AssocOp::AssignOp`, even though this allows some nonsensical combinations. E.g. there is no `&&=` operator. Likewise for HIR and THIR. This commit introduces `AssignOpKind` which only includes the ten assignable operators, and uses it in `ExprKind::AssignOp` and `AssocOp::AssignOp`. (And does similar things for `hir::ExprKind` and `thir::ExprKind`.) This avoids the possibility of nonsensical combinations, as seen by the removal of the `bug!` case in `lang_item_for_binop`. The commit is mostly plumbing, including: - Adds an `impl From<AssignOpKind> for BinOpKind` (AST) and `impl From<AssignOp> for BinOp` (MIR/THIR). - `BinOpCategory` can now be created from both `BinOpKind` and `AssignOpKind`. - Replaces the `IsAssign` type with `Op`, which has more information and a few methods. - `suggest_swapping_lhs_and_rhs`: moves the condition to the call site, it's easier that way. - `check_expr_inner`: had to factor out some code into a separate method. I'm on the fence about whether avoiding the nonsensical combinations is worth the extra code.

By replacing them with `{Open,Close}{Param,Brace,Bracket,Invisible}`.
PR #137902 made `ast::TokenKind` more like `lexer::TokenKind` by
replacing the compound `BinOp{,Eq}(BinOpToken)` variants with fieldless
variants `Plus`, `Minus`, `Star`, etc. This commit does a similar thing
with delimiters. It also makes `ast::TokenKind` more similar to
`parser::TokenType`.
This requires a few new methods:
- `TokenKind::is_{,open_,close_}delim()` replace various kinds of
pattern matches.
- `Delimiter::as_{open,close}_token_kind` are used to convert
`Delimiter` values to `TokenKind`.
Despite these additions, it's a net reduction in lines of code. This is
because e.g. `token::OpenParen` is so much shorter than
`token::OpenDelim(Delimiter::Parenthesis)` that many multi-line forms
reduce to single line forms. And many places where the number of lines
doesn't change are still easier to read, just because the names are
shorter, e.g.:
```
- } else if self.token != token::CloseDelim(Delimiter::Brace) {
+ } else if self.token != token::CloseBrace {
```

apparently it doesn't really use the asm parsing at present, so this may work?
Keep the `P` constructor function for now, to minimize immediate churn. All the `into_inner` calls are removed, which is nice.

…iscross Implement parsing of pinned borrows This PR implements part of #130494. EDIT: It introduces `&pin mut $place` and `&pin const $place` as sugars for `std::pin::pin!($place)` and its shared reference equivalent, except that `$place` will not be moved when borrowing. The borrow check will be in charge of enforcing places cannot be moved or mutably borrowed since being pinned till dropped. ### Implementation steps: - [x] parse the `&pin mut $place` and `&pin const $place` syntaxes - [ ] borrowck of `&pin mut|const` - [ ] support autoref of `&pin mut|const` when needed
New const traits syntax This PR only affects the AST and doesn't actually change anything semantically. All occurrences of `~const` outside of libcore have been replaced by `[const]`. Within libcore we have to wait for rustfmt to be bumped in the bootstrap compiler. This will happen "automatically" (when rustfmt is run) during the bootstrap bump, as rustfmt converts `~const` into `[const]`. After this we can remove the `~const` support from the parser Caveat discovered during impl: there is no legacy bare trait object recovery for `[const] Trait` as that snippet in type position goes down the slice /array parsing code and will error r? ``@fee1-dead`` cc ``@nikomatsakis`` ``@traviscross`` ``@compiler-errors``
Remove let_chains unstable feature Per rust-lang/rust#53667 (comment) (but then I also noticed rust-lang/rust#140722) This replaces the feature gate with a parser error that says let chains require 2024. A lot of tests were using the unstable feature. I either added edition:2024 to the test or split out the parts that require 2024.

test(rustfmt): Verify frontmatter is preserved This is to prove that the frontmatter is preserved. The choices in tests is intended for showing the different parts of the proposed Style Guide for frontmatters (rust-lang/rust#145617). While rustfmt is developed in a different repo, work involving upstream integration is blocked on some work that is being finished up in that repo.

Normally, changes to rustfmt go into the separate repo. But, in this case, the bug is introduced in a local change and therefore isn't present in the rustfmt repo.
add span to struct pattern rest (..) Struct pattern rest (`..`) did not retain span information compared to normal fields. This patch adds span information for it. The motivation of this patch comes from when I implemented this PR for Clippy: rust-lang/rust-clippy#15000 (comment) It is possible to get the span of the Et cetera in a bit roundabout way, but I thought this would be nicer.

mgca: Add ConstArg representation for const items tracking issue: rust-lang/rust#132980 fixes rust-lang/rust#131046 fixes rust-lang/rust#134641 As part of implementing `min_generic_const_args`, we need to distinguish const items that can be used in the type system, such as in associated const equality projections, from const items containing arbitrary const code, which must be kept out of the type system. Specifically, all "type consts" must be either concrete (no generics) or generic with a trivial expression like `N` or a path to another type const item. To syntactically distinguish these cases, we require, for now at least, that users annotate all type consts with the `#[type_const]` attribute. Then, we validate that the const's right-hand side is indeed eligible to be a type const and represent it differently in the HIR. We accomplish this representation using a new `ConstItemRhs` enum in the HIR, and a similar but simpler enum in the AST. When `#[type_const]` is **not** applied to a const (e.g. on stable), we represent const item right-hand sides (rhs's) as HIR bodies, like before. However, when the attribute is applied, we instead lower to a `hir::ConstArg`. This syntactically distinguishes between trivial const args (paths) and arbitrary expressions, which are represented using `AnonConst`s. Then in `generics_of`, we can take advantage of the existing machinery to bar the `AnonConst` rhs's from using parent generics.
…y-2025-12-06 Note that this merge conflict only makes `rustfmt` **buildable**, some tests (such as idempotency!) are still failing! # Merge conflict resolution - Manually retained `src/parse/macros/asm.rs` (upstream change is rust-lang/rust#140367, local removal was rust-lang#6698). - Several divergences between the `Option<String>` `rust-lang/rust` copy is stuck on, versus the `RewriteResult`s in `rustfmt` tree. When this happens, I changed the signature to use `RewriteResult` to match `rustfmt` tree. - Changed some helpers e.g. `offset_left` to `offset_left_opt`, while for others I had to add spans in places. Whenever this is needed, I take the `rustfmt` version as the "ground truth" and tried to keep close to `rustfmt`s version as much as possible. - There's a few place that I had to add `.unknown_error()` to to convert between missing snippets' `Option<usize>` to `RewriteResult` to match `rustfmt` tree's version. - Removed a few `.()`s to match `rustfmt` tree's version. - Changed a few `.rewrite()` to `.rewrite_result()`. - Changed a few `return None;` -> `Err(RewriteError::Unknown);`. - `format_trait_alias` is a bit non-trivial, the signature diverges. I modified the signature and body to match the `rustfmt` tree's version, because the rust copy's signature obviously does not have sufficient span info for rustfmt to work with. However, I also had to kinda mix-and-match, because the `rustfmt` tree's version did not have const formatting. - I had to improvise here and added a `constness: &ast::Const` parameter. - Please review carefully, this diverges from *both* copies! - Fixed a trivial conflict from removal of AST `P<>` (`item.into_inner()` -> `*item`). - Fixed removal of `TokenKind::{OpenDelim,CloseDelim}` with `TokenKind:: {OpenBrace,CloseBrace}` directly. - Changed `FmtVisitor::with_context` to the `rustfmt` version where `RewriteResult` is expected of the closure return. Also modified some `rw` -> `rw.ok()` to match `rustfmt`.
