Description of the problem:

Although the documentation refers the panic message in the same line with error message, the actual panic message is the next line of the error message with source code line that triggers error

Suggested fix:
The example output should be fixed with the actual output

The panic message style was changed in 1.73.0 to the one @Ian-sc-Kang attached. This book is currently based on 1.67.1. Updating the rustc version would solve this issue.
