-> **Note**
->
-> Configuration changes will not apply for code that has already been compiled and cached under `./target/`;
-> for example, adding a new string to `doc-valid-idents` may still result in Clippy flagging that string. To be sure
-> that any configuration changes are applied, you may want to run `cargo clean` and re-compile your crate from scratch.

 To deactivate the “for further information visit *lint-link*” message you can
 define the `CLIPPY_DISABLE_DOCS_LINKS` environment variable.
