Issue 種別: feature
難度: 3
推定時間: 1-3 hours
活動状況: blocked
明確さ: clear
前提条件: Rust genericsClippy lint development
初心者向け度: 50
調査方針: Examine the test case example comment at https://github.com/rust lang/rust clippy/issues/380#issuecomment 2862315757 to understand expected behavior. Look at existing similar lints in Clippy, such as those in clippy lints/src/, for pattern matching. The implementation should detect when a generic parameter name shadows a type name defined earlier in the same scope.
