Extend `implicit_saturating_sub` lint
Fixes#10070.
It can serve as base if we want to add equivalent checks for other arithmetic operations.
Also one important note: when writing this lint, I realized that I could check for wrong conditions performed beforehand on subtraction and added another part in the lint. Considering they both rely on the same checks, I kept both in the same place. Not sure if it makes sense though...
changelog: Extend `implicit_saturating_sub` lint
Misc changes to `clippy_config`
Contains part of #13084
Changes include:
* Sort config list and each configs lint list.
* Add default text for the two configs that were missing it.
* Switch the lint list in the configs to an attribute.
* Make `dev fmt` sort the config list.
r? `@xFrednet`
changelog: none
* Construct lint passes by taking `Conf` by reference.
* Use `HashSet` configs in less places
* Move some `check_crate` code into the pass constructor when possible.
* "AccessKit" is a commonly used accessibility toolkit used in Rust GUIs.
* "CoreFoundation", "CoreGraphics", "CoreText" are frameworks on Apple OSes.
* "Direct2D", "Direct3D", "DirectWrite" are frameworks on Windows
* "PostScript" is a programming language and is mentioned when talking about
text and vector graphics.
* "OpenAL" is an audio framework / API.
* "OpenType" is a font format (TrueType is already mentioned).
* "WebRTC", "WebSocket", "WebTransport" are web networking technologies.
* "NetBSD" and "OpenBSD" are like the already included FreeBSD.
Until now, the lint only emitted a warning, when breaking public API. Now it
doesn't lint at all when the config value is not set to `false`, bringing it in
line with the other lints using this config value.
Also ensures that this config value is documented in the lint.
Add configuration option for ignoring `panic!()` in tests
```
changelog: [`panic`]: Now can be disabled in tests with the `allow-panic-in-tests` option
```
I often find myself using `panic!(…)` in tests a lot, where I often do something like:
```rust
match enam {
Enam::A => …,
Enam::B => …,
_ => panic!("This should not happen at all."),
}
```
I think this patch should go nicely with already existing `allow-unwrap-in-tests` and `allow-expect-in-tests`.
make sure the msrv for `const_raw_ptr_deref` is met when linting [`missing_const_for_fn`]
fixes: #8864
---
changelog: make sure the msrv for `const_ptr_deref` is met when linting [`missing_const_for_fn`]
This adds a `àllow-useless-vec-in-test` configuration which, when set
to `true` will allow the `useless_vec` lint in `#[test]` functions and
code within `#[cfg(test)]`. It also moves a `is_in_test` helper to
`clippy_utils`.
[`module_name_repetition`] Recognize common prepositions
Fixes#12544
changelog: [`module_name_repetition`]: don't report an item name if it consists only of a prefix from `allowed-prefixes` list and a module name (e.g. `AsFoo` in module `foo`). Prefixes allowed by default: [`to`, `from`, `into`, `as`, `try_into`, `try_from`]
Fixes#12544.
- don't report an item name if it consists only of a prefix from `allowed-prefixes` list and a module name (e.g. `AsFoo` in module `foo`).
- configured by `allowed-prefixes` config entry
- prefixes allowed by default: [`to`, `from`, `into`, `as`, `try_into`, `try_from`]
- update docs
