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 :)

Fix `explicit_auto_deref` fp
fixes#9763fixes#9811
changelog: `explicit_auto_deref`: Don't lint when the target type is a projection with generic arguments
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)
Improve `needless_lifetimes`
This PR makes the following improvements to `needless_lifetimes`.
* It fixes the following false negative, where `foo` is flagged but `bar` is not:
```rust
fn foo<'a>(x: &'a u8, y: &'_ u8) {}
fn bar<'a>(x: &'a u8, y: &'_ u8, z: &'_ u8) {}
```
* It flags more cases, generally. Previously, `needless_borrow` required *all* lifetimes to be used only once. With the changes, individual lifetimes are flagged for being used only once, even if not all lifetimes are.
* Finally, it tries to produce more clear error messages.
changelog: fix `needless_lifetimes` false negative involving functions with multiple unnamed lifetimes
changelog: in `needless_lifetimes`, flag individual lifetimes used only once, rather than require all lifetimes to be used only once
changelog: in `needless_lifetimes`, emit "replace with `'_`" warnings only when applicable, and point to a generic argument
Add lint for confusing use of `^` instead of `.pow`
fixes#4205
Adds a lint named [`confusing_xor_and_pow`], it warns the user when `a ^ b` is used as the `.pow()` function, it doesn't warn for Hex, Binary... etc.

changelog: New lint: [`confusing_xor_and_pow`]
Warn when `clippy::restriction` is enabled via the command line
Currently it catches `#![warn(clippy::restriction)]`, it'll now catch `-W clippy::restriction` from the CLI. Also tweaks the message slightly
changelog: [`blanket_clippy_restriction_lints`]: Warn when `clippy::restriction` is enabled via the command line
fix `undocumented-unsafe-blocks` false positive
This fixes#9142 by iterating over the parent nodes as long as within a block, expression, statement, local, const or static.

Ensure new_ret_no_self is not fired if impl Trait<Self> is returned.
Fix#7344: ensure new_ret_no_self is not fired if `impl Trait<Self>` is returned.
changelog: [`new_ret_no_self`]: No longer lints when `impl Trait<Self>` is returned
[`use_self`] fix suggestion when full path to struct was given
Previously the following wrong suggestion was given
```rust
impl Error for std::fmt::Error {
fn custom<T: std::fmt::Display>(_msg: T) -> Self {
- std::fmt::Error // Should lint
+ Self::Error // Should lint
}
}
```
Also remove known problem line related to #4140 since it's been closed, and refactor the lint
