Navigate to detected problems

You can jump from one highlighted problem to another within a file by clicking in the widget or by pressing F2 or ShiftF2 accordingly. By default, the IDE will navigate you to problems according to their severity: errors > warnings > weak warnings > server problems > typos.

You can configure RustRover to take you through the problems one by one regardless of their severity. Hover over the widget in top-right corner of the editor, click , select 'Next Error' Action (F2) Goes Through, and enable All Problems.

Apart from viewing all problems in a single file, you can take a look at all problems detected across your entire project by using the project-wide analysis.

Project-wide analysis relies on external linter checks running on the fly. It also includes build errors.

note

For this feature to work, make sure on-the-fly linter analysis is turned on: you can do it using the widget in the status bar.

To view the results, open the Problems tool window Alt06 and switch to the Project Errors tab.

To jump to the corresponding line in the editor, press F4 or double-click the problem in the tool window.
