When a tuple-struct is re-exported that has inaccessible fields at the `use` scope, the type's constructor cannot be accessed through that re-export. We now account for this case and extend the resulting resolution error. We also check if the constructor would be accessible directly, not through the re-export, and if so, we suggest using the full path instead.
```
error[E0423]: cannot initialize a tuple struct which contains private fields

LL | let crate::Foo(x) = crate::Foo(42);

note: the type is accessed through this re-export, but the type's constructor is not visible in this import's scope due to private fields

resolve: Do not finalize shadowed bindings
I.e. do not mark them as used, or non-speculatively loaded, or similar.
Previously they were sometimes finalized during early resolution, causing issues like https://github.com/rust-lang/rust/pull/144793#issuecomment-3168108005.

Resolve: (Ref)Cell wrappers to deny mutation during spec resolution.
Introduces wrappers around `Cell` and `RefCell` that only allow mutation when we are not in speculative resolution. This is preparatory work for rust-lang/rust#145108.
It would allow us to make `ImportData` and `ModuleData` sync and send safe.

Use `Itertools::all_equal_value()` where applicable
Just a small cleanup.
We already have `itertools` as a dep in these crates, so might as well use another of its features.
Makes the code simpler IMHO :)

On unused binding or binding not present in all patterns, suggest potential typo of unit struct/variant or const
When encountering an or-pattern with a binding not available in all patterns, look for consts and unit struct/variants that have similar names as the binding to detect typos.
```
error[E0408]: variable `Ban` is not bound in all patterns

When encountering a typo in a pattern that gets interpreted as an unused binding, look for unit struct/variant of the same type as the binding:

```
Suggest constant on unused binding in a pattern
```

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: https://github.com/rust-lang/rust-clippy/pull/15000#discussion_r2134145163
It is possible to get the span of the Et cetera in a bit roundabout way, but I thought this would be nicer.

This was done in #145740 and #145947. It is causing problems for people
using r-a on anything that uses the rustc-dev rustup package, e.g. Miri,
clippy.
This repository has lots of submodules and subtrees and various
different projects are carved out of pieces of it. It seems like
`[workspace.dependencies]` will just be more trouble than it's worth.

Refactor lint buffering to avoid requiring a giant enum
Lint buffering currently relies on a giant enum `BuiltinLintDiag` containing all the lints that might potentially get buffered. In addition to being an unwieldy enum in a central crate, this also makes `rustc_lint_defs` a build bottleneck: it depends on various types from various crates (with a steady pressure to add more), and many crates depend on it.
Having all of these variants in a separate crate also prevents detecting when a variant becomes unused, which we can do with a dedicated type defined and used in the same crate.
Refactor this to use a dyn trait, to allow using `LintDiagnostic` types directly.
Because the existing `BuiltinLintDiag` requires some additional types in order to decorate some variants, which are only available later in `rustc_lint`, use an enum `DecorateDiagCompat` to handle both the `dyn LintDiagnostic` case and the `BuiltinLintDiag` case.
---
With the infrastructure in place, use it to migrate three of the enum variants to use `LintDiagnostic` directly, as a proof of concept and to demonstrate that the net result is a reduction in code size and a removal of a boilerplate-heavy layer of indirection.
Also remove an unused `BuiltinLintDiag` variant.
|
|
resolve: Remove `ScopeSet::Late`
It's better to decouple the late/early stage from scope set, because in https://github.com/rust-lang/rust/pull/144131#discussion_r2283200511 we'll need the stage for `ScopeSet::Module` as well.
See individual commits for the refactoring details.
r? ``@b-naber``

The difference between `Late` and `All` only matters when `finalize` is enabled.
So add a `stage` field to `Finalize` and use it instead.
|
|
|
|
It can be passed in a more usual way through `ParentScope`

Prevent impossible combinations in `ast::ModKind`.
`ModKind::Loaded` has an `inline` field and a `had_parse_error` field. If the `inline` field is `Inline::Yes` then `had_parse_error` must be `Ok(())`.
This commit moves the `had_parse_error` field into the `Inline::No` variant. This makes it impossible to create the nonsensical combination of `inline == Inline::Yes` and `had_parse_error = Err(_)`.
r? ```@Urgau```
|

`rustc_lint_defs` uses `rustc_hir` solely for the `Namespace` type,
which it only needs the static description from. Use the static
description directly, to eliminate the dependency on `rustc_hir`.
This reduces a long dependency chain:
- Many things depend on `rustc_errors`
- `rustc_errors` depends on `rustc_lint_defs`
- `rustc_lint_defs` depended on `rustc_hir` prior to this commit
- `rustc_hir` depends on `rustc_target`
