Jacob Pratt 1e6df58e77 Rollup merge of #140794 - karolzwolak:allow-unused-doc-65464, r=davidtwco ... mention lint group in default level lint note ### Summary This PR updates lint diagnostics so that default-level notes now mention the lint group they belong to, if any. Fixes: rust-lang/rust#65464. ### Example ```rust fn main() { let x = 5; } ``` Before: ``` = note: `#[warn(unused_variables)]` on by default ``` After: ``` = note: `#[warn(unused_variables)]` (part of `#[warn(unused)]`) on by default ``` ### Unchanged Cases Messages remain the same when the lint level is explicitly set, e.g.: * Attribute on the lint `#[warn(unused_variables)]`: ``` note: the lint level is defined here LL | #[warn(unused_variables)] | ^^^^^^^^^^^^^^^^ ``` * Attribute on the group `#[warn(unused)]:`: ``` = note: `#[warn(unused_variables)]` implied by `#[warn(unused)]` ``` * CLI option `-W unused`: ``` = note: `-W unused-variables` implied by `-W unused` = help: to override `-W unused` add `#[allow(unused_variables)]` ``` * CLI option `-W unused-variables`: ``` = note: requested on the command line with `-W unused-variables` ```		2025-08-20 00:45:53 -04:00
