the two loops did practically the same, only the type were different (&&
vs &), so I used `copied` to convert `&&` and chained them together.
Instead of parsing the trait info manually, I use the already provided
method `get_trait_info_from_bound`.
Also, instead of using manual string writing, I used `join` by
`itertools`.

Don't know how useful of a lint this is, just saw this was a really old issue 😄.

Add details about how significant drop in match scrutinees can cause deadlocks
Adds more details about how a significant drop in a match scrutinee can cause a deadlock and include link to documentation.
changelog: Add more details to significant drop lint to explicitly show how temporaries in match scrutinees can cause deadlocks.
Fix `#[expect]` for most clippy lints
This PR fixes most `#[expect]` - lint interactions listed in rust-lang/rust#97660. [My comment in the issue](https://github.com/rust-lang/rust/issues/97660#issuecomment-1147269504) shows the current progress (Once this is merged). I plan to work on `duplicate_mod` and `multiple_inherent_impl` and leave the rest for later. I feel like stabilizing the feature is more important than fixing the last few nits, which currently also don't work with `#[allow]`.

Add lint `explicit_auto_deref` take 2
fixes: #234fixes: #8367fixes: #8380
Still things to do:
* ~~This currently only lints `&*<expr>` when it doesn't trigger `needless_borrow`.~~
* ~~This requires a borrow after a deref to trigger. So `*<expr>` changing `&&T` to `&T` won't be caught.~~
* The `deref` and `deref_mut` trait methods aren't linted.
* Neither ~~field accesses~~, nor method receivers are linted.
* ~~This probably shouldn't lint reborrowing.~~
* Full slicing to deref should probably be handled here as well. e.g. `&vec[..]` when just `&vec` would do
changelog: new lint `explicit_auto_deref`
try reading rust-version from Cargo.toml
Cargo.toml can contain a field `rust-version`, that acts like a MSRV of
clippy.toml file: https://doc.rust-lang.org/cargo/reference/manifest.html#the-rust-version-field
This will try to read that field and use it, if the clippy.toml config
has no `msrv` entry
changelog: respect `rust-version` from `Cargo.toml`

`trivially_copy_pass_by_ref` fixes
fixes#5953fixes#2961
The fix for #5953 is overly aggressive, but the suggestion is so bad that it's worth the false negatives. Basically three things together:
* It's not obviously wrong
* It compiles
* It may actually work when tested
changelog: Don't lint `trivially_copy_pass_by_ref` when unsafe pointers are used.
changelog: Better track lifetimes when linting `trivially_copy_pass_by_ref`.

Thank you in advance.

enum_variant_names should ignore when all prefixes are _

Lint `[single_match]` on `Option` matches
fixes#8928
changelog: did some cleanup of the logic for ``[`single_match`]`` and ``[`single_match_else`]`` which fixes the bug where `Option` matches were not linted unless a wildcard was used for one of the arms.
