The `restriction` group contains many lints which are not about
necessarily “bad” things, but style choices — perhaps even style choices
which contradict conventional Rust style — or are otherwise very
situational. This results in silly wording like “Why is this bad?
It isn't, but ...”, which I’ve seen confuse a newcomer at least once.
To improve this situation, this commit replaces the “Why is this bad?”
section heading with “Why restrict this?”, for most, but not all,
restriction lints. I left alone the ones whose placement in the
restriction group is more incidental.
In order to make this make sense, I had to remove the “It isn't, but”
texts from the contents of the sections. Sometimes further changes
were needed, or there were obvious fixes to make, and I went ahead
and made those changes without attempting to split them into another
commit, even though many of them are not strictly necessary for the
“Why restrict this?” project.
Modify lint pass note for consistency with the book
This PR:
- removes the note which appears when an early lint pass is created using `cargo dev new_lint`.
- adds a note that encourages contributors to use an early pass unless type information is needed if a late lint pass is created using `cargo dev new_lint`.
Late pass remains the default value if no pass is specified as most lints use late pass.
Closes#12595
changelog: none
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
new lint `legacy_numeric_constants`
Rework of #10997
- uses diagnostic items
- does not lint imports of the float modules (`use std::f32`)
- does not lint usage of float constants that look like `f32::MIN`
I chose to make the float changes because the following pattern is actually pretty useful
```rust
use std::f32;
let omega = freq * 2 * f32::consts::PI;
```
and the float modules are not TBD-deprecated like the integer modules.
Closes#10995

[#12312](https://github.com/rust-lang/rust-clippy/pull/12312)
RFC: Document Clippy's teams and team duties
First the big announcement:
**We want to add a new subteam for regular contributors to give them triage rights.**
---
This PR adds a new section to the book which describes the Clippy and Clippy-Contributor teams, with their duties and membership requirements. This is just an initial draft, that outlines what, I think, their responsibilities should be.
I hope everyone in the team is okay with me posting this directly to GitHub. I think a PR makes collaboration a bit easier.
[🖼️ Rendered 🖼️](https://github.com/xFrednet/rust-clippy/blob/add-team-docs/book/src/development/the_team.md)
---
Once we've decided on this document, I'll create a PR to add the new team on GitHub. As part of this, we'll also reach out to some active contributors, to ask if they would like to join the new team.

r? `@flip1995`
Several (doc) comments were super outdated or didn't provide enough context.
Some doc comments shoved everything in a single paragraph without respecting
the fact that the first paragraph should be a single sentence because rustdoc
treats these as item descriptions / synopses on module pages.
I want to be clear: this is just the initial draft outlining what, I think, should be the responsibilities of the team members. It has not yet been discussed with anyone else.
