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.

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
r? `@Jarcho`
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`]

Move needless_collect to nursery
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: [`needless_collect`]: Move `needless_collect` to nursery (Now allow-by-default)
After chatting with a few folks, it seems like `needless_collect` is giving false positives pretty regularly (https://github.com/rust-lang/rust-clippy/issues?q=is%3Aissue+is%3Aopen+needless_collect). We're big supporters of clippy in Nushell, and it's one of the passes we require for CI, but we've had to disable this particular lint. Perhaps it should be moved to the nursery until it's improved?
(apologies if this isn't the right approach to disabling a lint by default. I tried to follow the idea I saw other PRs doing in the past)
