Extend `needless_borrowed_reference` to structs and tuples, ignore _
changelog: [`needless_borrowed_reference`]: Lint struct and tuple patterns, and patterns containing `_`
Now lints patterns like
```rust
&(ref a, ref b)
&Tuple(ref a, ref b)
&Struct { ref a, ref b }
&(ref a, _)
```
Fix typo in `expect_used` and `unwrap_used` warning messages
"\`an Option\`" -> "an \`Option\`" and "\`a Result\`" -> "a \`Result\`".

`never_loop`: don't emit AlwaysBreaks if it targets a block
ref: https://github.com/rust-lang/rust-clippy/pull/9837#issuecomment-1312788194
The previous fix (#9837) was too simple and ignored all break commands inside a labelled block, regardless of whether their destination was a labelled block or a loop. This fix tracks all the labelled blocks in scope to ensure that only breaks targeting loops are considered.
changelog: [`never_loop`]: prevent false negatives from `breaks` nested in labelled blocks
Introduced an ignored_ids parameter.
Takes O(n^2) time in the worst case.
Can be changed to collect block ids in first phase,
and then filter with binary search in second.
feat: lint unchecked subtraction of a 'Duration' from an 'Instant'
Hello all, I tried to tackle the open issue #9371 and this is what I came up with.
I have a difficulty currently - some tests are failing:
```
failures:
[ui] ui/manual_instant_elapsed.rs
```
The `manual_instant_elapsed` is failing because of `Instant::now() - duration` test, this now gets also picked by `unchecked_duration_subtraction` lint.
What is the correct way to proceed in this case? Simply update the `.stderr` file for `manual_instant_elapsed` lint?
changelog: [`unchecked_duration_subtraction`]: Add lint for unchecked subtraction of a `Duration` from an `Instant`.

Make it clear that `or_fun_call` can be a false-positive
Also move it to nursery so that the false-positives can be dealt with.
CC #8574
changelog: [`or_fun_call`]: Mention false-positives, move to nursery.
Add `unnecessary_safety_doc` lint
changelog: [`unnecessary_safety_doc`]: Add `unnecessary_safety_doc` lint
fixes https://github.com/rust-lang/rust-clippy/issues/6880
This lint does not trigger for private functions, just like `missing_safety_docs`. Reason for that was implementation simplicity and because I figured asking first would make more sense, so if it should trigger for private functions as well let me know and I'll fix that up as well.
[`fn_params_excessive_bools`] Make it possible to allow the lint at the method level
changelog: FP: [`fn_params_excessive_bools`]: `#[allow]` now works on methods
fix https://github.com/rust-lang/rust-clippy/issues/9687
Tested without committing but `#[allow]`ing now works. Also rewrote the lint to be a late lint while at it :)

Address issues 9739 and 9782
This PR fixes#9739 in the manner I suggested in https://github.com/rust-lang/rust-clippy/issues/9739#issuecomment-1296802376.
This PR also fixes the compilation failures in #9782 (but doesn't address `@e00E's` other objections).
Fixes#9739

changelog: Fix two `needless_borrow` false positives, one involving borrows in `if`-`else`s, the other involving qualified function calls
Add `manual_is_ascii_check` lint
Addresses https://github.com/rust-lang/rust-clippy/issues/9290
This PR adds new lint `manual_is_ascii_check`, which detects comparison with ascii ranges using `matches!` macros.
As I mentioned as following in the Issue;
> Yes, that's true. we'll start small and then grow it.
> So I'll try to handle matches! macro with single range as suggested above.
However during writing first version, I was thinking that the changes to support alphabetic and digits will be small patch, so I made a single PR in hope review cost can be reduced.
changelog: add new lint [`manual_is_ascii_check`]
