Before writing any code, change your Word Wrap setting to "wordWrapColumn": 80 in your VSCode settings. This is essential, as our CdC requires the project to respect the 80 characters per line rule. If you have any questions about this procedure, ask on the group's Discord server.
To test the nexium_client package, use cargo tauri dev instead of cargo run. This will start the Tauri application and allow you to test the client.
