Limit the ``[`identity_op`]`` lint to integral operands.
changelog: limit ``[`identity_op`]`` to integral operands
In the ``[`identity_op`]`` lint, if the operands are non-integers, then the lint is likely
wrong.
Fixed issues with to_radians and to_degrees lints
fixes#7651
I fixed the original problem as described in the issue, but the bug remains for complex expressions (the commented out TC I added is an example). I would also love some feedback on how to cleanup my code and reduce duplication. I hope it's not a problem that the issue has been claimed by someone else - that was over two months ago.
changelog: ``[`suboptimal_flops`]`` no longer proposes broken code with `to_radians` and `to_degrees`
Fix `enum_variants` FP on prefixes that are not camel-case
closes#8090
Fix FP on `enum_variants` when prefixes are only a substring of a camel-case word. Also adds some util helpers on `str_utils` to help parsing camel-case strings.
This changes how the lint behaves:
1. previously if the Prefix is only a length of 1, it's going to get ignored, i.e. these were previously ignored and now is warned
```rust
enum Foo {
cFoo,
cBar,
cBaz,
}
enum Something {
CCall,
CCreate,
CCryogenize,
}
```
2. non-ascii characters that doesn't have casing will not be split,
```rust
enum NonCaps {
PrefixXXX,
PrefixTea,
PrefixCake,
}
```
will be considered as `PrefixXXX`, `Prefix`, `Prefix`, so this won't lint as opposed to fired previously.
changelog: [`enum_variant_names`] Fix FP when first prefix are only a substring of a camel-case word.

(Edited by `@xFrednet` removed some non ascii characters)
closes#8177
previously, `needless_return` suggests an empty block `{}` to replace void `return` on match arms, this PR improve the suggestion by suggesting a unit instead.
changelog: `needless_return` suggests `()` instead of `{}` on match arms
`enum_variant_names` will consider characters with no case to be a part
of prefixes/suffixes substring that are compared. This means `Foo1` and
`Foo2` has different prefixes (`Foo1` and `Foo2` prefix respeectively).
This applies to all non-ascii characters with no casing.
fix an ICE on unwrapping a None
This very likely fixes#8166 though I wasn't able to meaningfully reduce a test case. This line is the only call to `unwrap` within that function, which was the one in the stack trace that triggered the ICE, so I think we'll be OK.
`@hackmad` can you pull and build this branch and check if it indeed fixes your problem?

Fix `SAFETY` comment tag casing in undocumented_unsafe_blocks
This changes the lint introduced in #7748 to suggest adding a `SAFETY` comment instead of a `Safety` comment.
Searching for `// Safety:` in rust-lang/rust yields 67 results while `// SAFETY:` yields 1072.
I think it's safe to say that this comment tag is written in upper case, just like `TODO`, `FIXME` and so on are. As such I would expect this lint to follow the official convention as well.
Note that I intentionally introduced some casing diversity in `tests/ui/undocumented_unsafe_blocks.rs` to test more cases than just `Safety:`.
changelog: Capitalize `SAFETY` comment in [`undocumented_unsafe_blocks`]
Don't emit RETURN_SELF_NOT_MUST_USE lint if `Self` already is marked as `#[must_use]`
New bug discovered with this lint. Hopefully, this is the last one.

changelog: none
Ensure that RETURN_SELF_NOT_MUST_USE is not emitted if the method already has `#[must_use]`
Fixes https://github.com/rust-lang/rust-clippy/issues/8140.

Edit:
changelog: none
(The lint is not in beta yet, this should therefore not be included inside the changelog :) )
Stabilize `iter::zip`
Hello all!
As the tracking issue (#83574) for `iter::zip` completed the final commenting period without any concerns being raised, I hereby submit this stabilization PR on the issue.
As the pull request that introduced the feature (#82917) states, the `iter::zip` function is a shorter way to zip two iterators. As it's generally a quality-of-life/ergonomic improvement, it has been integrated into the codebase without any trouble, and has been
used in many places across the rust compiler and standard library since March without any issues.
For more details, I would refer to `@cuviper's` original PR, or the [function's documentation](https://doc.rust-lang.org/std/iter/fn.zip.html).
