Start the debugger session
Starting a debugger session is very similar to running the program in normal mode. The debugger is attached behind the scenes, so you don't have to configure anything specific to start a debugger session. If you are able to run your program from RustRover, you will also be able to debug it using the same configuration.
Any debugger session is based on a run/debug configuration. The configuration type depends on the type of your application and the runtime environment.
Click
next to the desired entry point and select Debug.
This will create a temporary run/debug configuration for you. After that, you can customize and save this temporary configuration if needed.
If you already have a run/debug configuration, select it from the run/debug configurations list and click the
button or press Shift+F9.
Pause/Resume a debugger session
When the debugger session is running, you can pause/resume it as required using the buttons on the toolbar of the Debug tool window:
To pause a debugger session, click
.To resume a debugger session, click
F9.
Restart a debugger session
Click the
Rerun button in the Debug tool window or press Ctrl+F5.
Terminate a debugger session
Click the
Stop button in the Debug tool window.Alternatively, press Ctrl+F2 and select the process to terminate (if there are two or more of them).
Productivity tips
- Debug non-responding applications
In case your application hung, pause the session to let the debugger get the information about its current state. You can then examine the program state and locate the cause of the problem.
- Do more with pause
When you need to evaluate an expression, and RustRover doesn't let you do that because you didn't stop at a breakpoint, you can advance your program a line further by stepping. After this, you will be able to use the debugger as if you had stopped at a breakpoint. While in some cases this may not be a valid solution, it may sometimes help you out.
