RS.CLIPPY.UNNECESSARY_CLIPPY_CFG

Usage of `cfg_attr(clippy, allow(clippy::lint))` instead of `allow(clippy::lint)`

This checker is a Clippy lint created by The Rust Project Contributors. The documentation shown here is a copy of the original documentation for: unnecessary_clippy_cfg. Copyright ©2025 The Rust Team. All rights reserved.

What it does

Checks for #[cfg_attr(clippy, allow(clippy::lint))] and suggests to replace it with #[allow(clippy::lint)].

Why is this bad?

There is no reason to put clippy attributes behind a clippy cfg as they are not run by anything else than clippy.

Example

#![cfg_attr(clippy, allow(clippy::deprecated_cfg_attr))]

Use instead:

#![allow(clippy::deprecated_cfg_attr)]
