Pause PR assignments for xFrednet :)
My life is currently a bit chaotic, and it feels like I can't give reviews the attention they need. I'll finish the PRs I'm assigned to, write the changelogs, and am available when I get pinged etc.
This is only intended as a temporary pause, as I still genuinely enjoy working with everyone in this repo and seeing Clippy grow day by day.

Take lifetime extension into account in `ref_as_ptr`
fixes#12255
This should be merged upstream as well. Changing `let x = &temp as *const _` into `let x = from_ref(&temp)` is UB.

Allow unused_imports, and unused_import_braces on `use`
Fixes https://github.com/rust-lang/rust-clippy/issues/12223.
Both `unused_import_braces` and `unused_imports` are valid on `use`-items, additional to the two previously allowed.

Coming back to reviewer rotation
After this current CPP period, in which I set myself as on-vacation to focus on performance, I'm now available again. I'd love if my vacation status wasn't present in version control

Add check for 'in_external_macro' and 'is_from_proc_macro' inside

Added an in_external_macro and is_from_proc_macro check to the [infinite_loop] lint
Extend `unnecessary_to_owned` to handle `Borrow` trait in map types
Fixes https://github.com/rust-lang/rust-clippy/issues/8088.
Alternative to #12315.

Fix: no_effect_underscore_binding fires on ignored parameters of async fns
Fixes#12279
changelog: Fix [`no_effect_underscore_binding`])
The warning is no longer displayed when an underscore is given in the parameter name of an asynchronous function.

UPDATE: add async block into test.
FIX: no_effect
Fixed asynchronous function parameter names with underscores so that warnings are not displayed when underscores are added to parameter names
ADD: test case
Overhaul `Diagnostic` and `DiagnosticBuilder`
Implements the first part of https://github.com/rust-lang/compiler-team/issues/722, which moves functionality and use away from `Diagnostic`, onto `DiagnosticBuilder`.
Likely follow-ups:
- Move things around, because this PR was written to minimize diff size, so some things end up in sub-optimal places. E.g. `DiagnosticBuilder` has impls in both `diagnostic.rs` and `diagnostic_builder.rs`.
- Rename `Diagnostic` as `DiagInner` and `DiagnosticBuilder` as `Diag`.
r? `@davidtwco`
Always evaluate free constants and statics, even if previous errors occurred
work towards https://github.com/rust-lang/rust/issues/79738
We will need to evaluate static items before the `definitions.freeze()` below, as we will start creating new `DefId`s (for nested allocations) within the `eval_static_initializer` query.
But even without that motivation, this is a good change. Hard errors should always be reported and not silenced if other errors happened earlier.
Currently many diagnostic modifier methods are available on both
`Diagnostic` and `DiagnosticBuilder`. This commit removes most of them
from `Diagnostic`. To minimize the diff size, it keeps them within
`diagnostic.rs` but changes the surrounding `impl Diagnostic` block to
`impl DiagnosticBuilder`. (I intend to move things around later, to give
a more sensible code layout.)
`Diagnostic` keeps a few methods that it still needs, like `sub`,
`arg`, and `replace_args`.
The `forward!` macro, which defined two additional methods per call
(e.g. `note` and `with_note`), is replaced by the `with_fn!` macro,
which defines one additional method per call (e.g. `with_note`). It's
now also only used when necessary -- not all modifier methods currently
need a `with_*` form. (New ones can be easily added as necessary.)
All this also requires changing `trait AddToDiagnostic` so its methods
take `DiagnosticBuilder` instead of `Diagnostic`, which leads to many
mechanical changes. `SubdiagnosticMessageOp` gains a type parameter `G`.
There are three subdiagnostics -- `DelayedAtWithoutNewline`,
`DelayedAtWithNewline`, and `InvalidFlushedDelayedDiagnosticLevel` --
that are created within the diagnostics machinery and appended to
external diagnostics. These are handled at the `Diagnostic` level, which
means it's now hard to construct them via `derive(Diagnostic)`, so
instead we construct them by hand. This has no effect on what they look
like when printed.
There are lots of new `allow` markers for `untranslatable_diagnostics`
and `diagnostics_outside_of_impl`. This is because
`#[rustc_lint_diagnostics]` annotations were present on the `Diagnostic`
modifier methods, but missing from the `DiagnosticBuilder` modifier
methods. They're now present.
Default test output conflict handling to error
https://github.com/oli-obk/ui_test/pull/175 got rid of the `bool` that controlled the default handling so we need to specify it ourselves

Fix issue 11223: add check for identical guards in lint `match_same_arms`
fixes#11223
In the current `match_same_arms` implementation, if arms have guards, they are considered different. This commit adds equality checking for guards: arms are now considered equivalent only when they either both have no guards or their guards are identical.
The portion responsible for checking guard equality is refactored to reuse the existing code for checking body equality. This is abstracted into a function called `check_eq_with_pat`. To optimize performance, `check_same_guard` and `check_same_body` here use closures for lazy evaluation, ensuring that the calculation is only performed when `!(backwards_blocking_idxs...)` is true.
changelog: [`match_same_arms`]: Add check for identical guards
There are lots of functions that modify a diagnostic. This can be via a
`&mut Diagnostic` or a `&mut DiagnosticBuilder`, because the latter type
wraps the former and impls `DerefMut`.
This commit converts all the `&mut Diagnostic` occurrences to `&mut
DiagnosticBuilder`. This is a step towards greatly simplifying
`Diagnostic`. Some of the relevant function are made generic, because
they deal with both errors and warnings. No function bodies are changed,
because all the modifier methods are available on both `Diagnostic` and
`DiagnosticBuilder`.
Remove `$DIR` replacement
This won't cause problems because the old `$DIR` replacement was based on the parent of the test path, which for us is relative: 5471e0645a/tests/compile-test.rs (L122)
The new pattern being `"tests/{test_dir}"` is more clearly relative
That's why we have custom filters applied to the toml/cargo tests where absolute paths do appear in the output 5471e0645a/tests/compile-test.rs (L198-L202)
Removing it allows clicking the paths in the terminal

fix: make `#[allow]` work on field for `pub_underscore_fields`
Closes#12286
changelog: `#[allow(clippy::pub_underscore_fields)]` now works on linted field
fixes#117448
For example unnecessary imports in std::prelude that can be eliminated:
```rust
use std::option::Option::Some;//~ WARNING the item `Some` is imported redundantly
use std::option::Option::None; //~ WARNING the item `None` is imported redundantly
```
