Disable and suppress inspections

Some inspections may report problems that you currently do not want to see. In this case, you can disable or suppress them.

Disable inspections

When you disable an inspection, you turn it off. It means that the code analysis engine stops searching project files for the problem that this inspection is designed to detect. Note that when you disable an inspection, you disable it in the current inspection profile; it remains enabled in other profiles.

Most inspections in RustRover can be disabled. However, some inspections will keep highlighting your code regardless of the settings. For example, syntax errors are always highlighted.

Disable an inspection in settings

  1. Press Ctrl+Alt+S to open settings and then select Editor | Inspections.

  2. Locate the inspection you want to disable, and clear the checkbox next to it.

    Enable inspection
  3. Apply the changes and close the dialog.

Disable an inspection from the editor

  1. Place the caret at the highlighted line and press Alt+Enter (or click the Intention action icon to use the intention action).

  2. Click the arrow next to the inspection you want to disable, and select Disable inspection.

    Disable an inspection in the editor

Disable an inspection from the Problems tool window

  1. In the Inspection Results tab of the Problems tool window (appears once you run code analysis), right-click the inspection you want to disable and select Disable inspection.

  2. Click the Filter resolved items icon to hide the disabled inspection alerts.

Suppress inspections

When you suppress an inspection, the code analysis engine doesn't highlight the problem found by this inspection in the specific piece of code. You can also suppress all inspections in the current item.

Most inspections in RustRover can be suppressed. However, some inspections do not have this option. For example, syntax errors are always highlighted in the editor regardless of the settings.

Suppress an inspection from the editor

  1. Place the caret at the highlighted line and press Alt+Enter (or click the Intention action icon to use the intention action).

  2. Click the button next to the inspection you want to suppress and select the suppress action according to the required scope.

Disable highlighting, but keep the fix

Inspections have severities according to which they highlight code problems in the editor. You can quickly disable code highlighting for an inspection without opening the settings. In this case, the inspection remains enabled and provides a fix, but the severity changes to No highlighting (fix available).

  1. Place the caret at a code element highlighted by an inspection in the editor and press Alt+Enter.

    A list with available fixes and context actions opens. Locate the inspection fix that is marked with Intention action icon.

  2. Click the button next to the fix to open the inspection's options and select Disable highlighting, keep fix.

    Disable highlighting, keep the fix

If you want to restore the highlighting, press Ctrl+Alt+S to open the IDE settings and select Editor | Inspections. Find the necessary inspection in the list and change its severity as you like. For more information, refer to Change inspection severity in all scopes.

Change the highlighting level for a file

  • By default, RustRover highlights all detected code problems. Hover over the widget in the top-right corner of the editor and select another level from the Highlight list:

    • None: turn highlighting off.

    • Syntax: highlight syntax problems only.

    • All Problems: (default) highlight syntax problems and problems found by inspections.

  • You can also change the highlighting level from the main menu. Select Code | Analyze Code | Configure Current File Analysis or press Ctrl+Alt+Shift+H.
