fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

async fn run(self, subsys: &mut SubsystemHandle) -> Result<(), NeverError>

The logic of the subsystem.

fn into_subsystem( self, ) -> impl FnOnce(&mut SubsystemHandle<ErrWrapper>) -> Pin<Box<dyn Future<Output = Result<(), Err>> + Send + '_>>

Converts the object into a type that can be passed into SubsystemHandle::start().
