Find unused/irelevant clippy annotations

[SylvainDe]

What it does

Here is the use case:

1. I define an entity which causes a defect found by clippy
2. I add a temporary annotation to to be able to run clippy and ensure that new defects are quickly found and fixed
3. I fix the original defect and I completely forget about remove the clippy annotation

-> The clippy annotation is useless but on top of that:

• can be confusing
• can hide issues added to the code later on

Lint Name

useless-clippy-annotation

Category

pedantic

Advantage

Get rid of useless clippy annotations

Drawbacks

I do not know the clippy internals and thus, I have no idea if this can be easy to implement

Example

I tend to have the problem with "#[allow(clippy::missing_const_for_fn)]" which I use when prototyping and then forget to remove.

This is being added to rust as #[expect(...)] rust-lang/rust#54503
