Rewrite [`tuple_array_conversions`]
Fixes#11100Fixes#11144Fixes#11124#11082 still needs discussion and #11085 likely can't be fixed.
changelog: [`tuple_array_conversions`]: Move to `pedantic`
changelog: [`tuple_array_conversions`]: Don't lint if mutability of references changes
changelog: [`tuple_array_conversions`]: Don't lint if bindings don't come from the exact same pattern
changelog: [`tuple_array_conversions`]: Don't lint if bindings are used for more than just the conversion
new lint: `format_collect`
A perf lint that looks for `format!`ing inside of `map`, then collecting it into a `String`. Did a quick benchmark locally and it's a bit more than 2x faster with fold.
`write!` is still not optimal (presumably because the fmt stuff goes through dynamic dispatch), but it's still a lot better than creating a new string on every element.
I thought about making a machine applicable suggestion, but there's a lot of suggestions that need to be made here, so I decided to just add help messages.

don't hide lifetimes for `LateContext`
Running `cargo dev new_lint --type methods` creates the lint file with hidden lifetimes for the `LateContext` parameter (i.e. `&LateContext`, when it should be `&LateContext<'_>`). This is already warned on with `#![warn(rust_2018_idioms)]`, so clippy should not use hidden lifetimes

Trigger a rebuild when `CLIPPY_CONF_DIR` changes
changelog: none
This is a fix for https://github.com/rust-lang/rust-clippy/issues/9928#issuecomment-1634698183, any time `CLIPPY_CONF_DIR` changes cargo will now rebuild the crate clippy is being run on, giving it a chance to lint with the (potentially) different config file
r? `@flip1995`
Add `imports_granularity = "Module"` to rustfmt.toml
This lets rustfmt split/merge imports, `Module` seems to be the most common style in clippy
https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#imports_granularity
changelog: none
Almost all the updates other than the config file change are from `cargo dev fmt` or blessed tests, the exceptions being
- `tests/ui/single_component_path_imports.rs`
- `tests/ui/single_component_path_imports_nested_first.rs`
- `tests/ui/single_component_path_imports_self_after.rs`
- `tests/ui/single_component_path_imports_self_before.rs`
- `tests/ui/unsafe_removed_from_name.rs` (added a test with merged imports as a drive by)
- `tests/ui/wildcard_imports.rs`
- `tests/ui/wildcard_imports_2021.rs`
[`arithmetic_side_effect`]: allow different types on the right hand side for `Wrapping<T>`
Fixes#11145
This lint has a list of allowed types, one of which is `Wrapping<T>`, but it was only actually allowed if the type on the right hand side was also `Wrapping<T>`, which meant that, for example, `Wrapping<u32> += u32` would still lint. It now allows binary ops involving `Wrapping<T>` regardless of the type on the rhs.
These impls have only existed since Rust 1.60.0, so that is probably why the lint was previously not handling this correctly
changelog: [`arithmetic_side_effect`]: allow different types on the right hand side for `Wrapping<T>` (e.g. `Wrapping<T> += T`)
Add "Known problems" section to `needless_borrow` documentation
While this PR doesn't fix the issue in #11142, it at least communicates that this is a known limitation.

Hey `@rust-lang/clippy,` `@blyxyas,` and `@Centri3,` I've tried the "new"/minimal changelog format we discussed a few meetings ago. I like it, and the writing process was also way quicker.
[🖼️ Rendered 🖼️](https://github.com/xFrednet/rust-clippy/blob/changelog-1-71/CHANGELOG.md#rust-171)
Furthermore, a big thank you to `@blyxyas` and `@Alexendoo` for updating the script that fetches the PR commits and adding links to the config values to the changelog. ❤️
