fn dry_run<'life0, 'life1, 'async_trait>( &'life0 self, _patient: &'life1 PatientApp, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Return a detailed description of what this fix will do, such as a file diff or list of commands to be executed.
