Allow registering tool lints with `register_tool` Previously, there was no way to add a custom tool prefix, even if the tool itself had registered a lint: ``` #![feature(register_tool)] #![register_tool(xyz)] #![warn(xyz::my_lint)] ``` ``` $ rustc unknown-lint.rs --crate-type lib error[E0710]: an unknown tool name found in scoped lint: `xyz::my_lint` --> unknown-lint.rs:3:9 \| 3 \| #![warn(xyz::my_lint)] \| ^^^ ``` This allows opting-in to lints from other tools using `register_tool`. 2021-03-16 21:33:03 +00:00			//~^ ERROR unknown tool name `foo` found in scoped lint: `foo::bar`
