Summary

Documentation of as_pointer_underscore claims it is available in 1.81.0, but it is not present in 1.83.0
https://rust-lang.github.io/rust-clippy/master/index.html#/as_pointer_underscore

Reproducer

I tried this code:

% cargo clippy --version
clippy 0.1.83 (90b35a62 2024-11-26)
% cargo clippy --explain as_pointer_underscore
unknown lint: as_pointer_underscore
%

I expected to see this happen:
The explanation of the lint to be given. (According to the documentation, I should be able to do this a 1.81.0.)

Instead, this happened:
unknown lint: as_pointer_underscore reported.

This lint was introduced with #13251, two weeks ago, so it's not part of 1.83.0, and certainly not 1.81.0. The 1.81.0 version is probably due to the fact that the PR was opened much earlier. On the other hand, the version of newly added lints is corrected in new releases, as described in 4. Update clippy::version attributes.

Since you are using the 1.83.0 version, you should look for lints in https://rust-lang.github.io/rust-clippy/rust-1.83.0/index.html, which does not contain as_pointer_underscore, instead of https://rust-lang.github.io/rust-clippy/master/index.html. In general, one can start from https://rust-lang.github.io/rust-clippy/ and choose the correct version.

I have also encountered this problem, especially when clicking on links from search results for Clippy Lints. Perhaps there should be a noticeable difference between Clippy Lints (stable) and Clippy Lints (master), apart from the different URL. Much like the difference between std (stable) and std (internal).
