Interactive debugger console

Run JavaScript in the Console

1. Start typing a statement at > in the input field. As you type, RustRover suggests variants for completion.

2. Select the relevant statement and press Enter. RustRover shows its value in the console.

   RustRover shows previews for objects, so you do not need to expand them. If you still expand an object, you get an overview of just its own properties, the __proto__ contents are hidden by default.

Navigate to source code

• At each line with output of console.*, RustRover shows the name of the file and the line where it was called. Click this link to jump to the call in the source code.

  

• The Console also shows stack traces. Click the link next to a reported problem to jump to the line of code where this problem occurred.

  

Filter out messages

The Console tab shows objects in a tree view, with stack traces collapsed by default. Warnings console.warn(), errors console.error(), and info console.info() messages have different icons and background colors to make them easier to notice.

• To hide log messages of specific types, click and select the severities to filter out.

  

Group messages

• The log messages grouped using console.group() and console.groupEnd() are displayed as a tree. To show the output collapsed by default, use console.groupCollapsed().

  

Apply CSS styles

• Use CSS and the %c marker to apply styles to log messages.
