Use AI prompts to explain and refactor your code

Use pre-written prompts to explain code, refactor, and find problems in your code. RustRover provides project-specific context, such as the languages and technologies used in your project.

You can also define your own custom prompts and add them to the AI Actions menu.

In the field with the refactored code, click Show Diff to open the diff viewer. To skip the diff viewing step, expand the list next to Show Diff and select Apply Immediately.
In the diff viewer, use Unified or Two-Side view to review the suggested changes.
If you like the result, click Accept in the gutter to move the selected AI-generated code snippets to the source file, or click Accept all to fully replace the originally selected code fragment. Otherwise, close the diff viewer to skip the suggested refactoring.

Add your own prompts to prompts library

You can add your own prompts to the prompts library and use them via the AI Actions menu.

Do one of the following:
- Right-click anywhere in the editor to open the context menu, then go to AI Actions | Add Your Prompts.
- Press Alt+Enter, select AI Actions, and click Add your prompts.
- Press Ctrl+Alt+S to open settings and then select Tools | AI Assistant | Prompt Library.
Click to create a new prompt.
In the text field, write the prompt.
If needed, click the $SELECTION variable to add a Markdown-formatted code block with current code selection and language name to the new prompt.
Edit the new prompt name.
Select the first checkbox if you want AI Assistant to wait for you to make additional input in the chat after invoking the prompt.
Keep the second checkbox if you want your new prompt to be listed in the AI Actions menu.
Click Apply.

Once you create a prompt, you can edit or delete it at any time.

You can also select a prompt from the list and move it up or down to change the order in which the prompts are displayed.
