4. Click Apply.

Before proceeding, check whether on-the-fly analysis is turned on or off.

• If on-the-fly analysis is turned off, to call the linter, open the Cargo tool window (View | Tool Windows | Cargo) and click .

  

Information about detected issues will appear in the Problems tool window, together with inspection results.
