You could make this return an option of the first segment and then use that segment in the is_known_lint_tool
function (and maybe to use a more fine-grained span for the diagnostic)

Yeah good idea!

Implementation of tool lints. Tracking issue: #44690
☀️ Test successful - status-appveyor, status-travis |
Make the tool_lints actually usable cc rust-lang#44690 Necessary for rust-lang/rust-clippy#2955 and rust-lang/rust-clippy#2977 This PR makes it possible for lint tools (at the moment only for Clippy) to implement the `tool_lints`, like it was documented in rust-lang#52018. Because the `declare_lint` macro is pretty cluttered right now, there was not really a good way to add the `tool_name` as an additional argument of the macro. That's why I chose to introduce the new `declare_tool_lint` macro. The switch from `&str` to `String` in the `lint_groups` `FxHashMap` is because I got weird error messages in the `check_lint_name` method. And the `by_name` field of the `LintStore` also uses `String`. ### What comes with this PR: If this PR lands and Clippy switches to the `tool_lints`, the currently used methods ```rust #[cfg_attr(feature = "cargo-clippy", allow(clippy_lint))] #[allow(unknown_lints, clippy_lint)] ``` to `allow`/`warn`/`deny`/`forbid` Clippy lints, won't have any effects anymore, but also won't produce a warning. That is because the name of `clippy_lint` will then be `clippy::clippy_lint`. (Maybe we can add a clippy lint to search for `cfg_attr` appearances with the `cargo-clippy` feature?) r? @oli-obk
