There was a problem hiding this comment.
I prefer the name raw pointer, but anyway, the point of this function is to index the vector without boundary checking, and that's the unsafe part of it.

Don't lint `needless_return` if `return` has attrs Fixes rust-lang#9361 The lint used to have a mechanic to allow `cfg`-attrs on naked `return`-statements. This was well-intentioned, yet we can have any kind of attribute, e.g. `allow`, `expect` or even custom `derive`. So the mechanic was simply removed. We now never lint on a naked `return`-statement that has attributes on it. Turns out that the ui-test had a Catch22 in it: In `check_expect()` the `#[expect(clippy::needless_return)]` is an attribute on the `return` statement that can and will be rustfixed away without side effects. But any other attribute would also have been removed, which is what rust-lang#9361 is about. The test proved the wrong thing. Removed the test, the body is tested elsewhere as well. changelog: Ignore [`needless_return`] on `return`s with attrs
