Trait polkadot_overseer::Subsystem

pub trait Subsystem<Ctx, E> where
    Ctx: SubsystemContext,
    E: 'static + Error + Send + Sync + From<OverseerError>, {
    fn start(self, ctx: Ctx) -> SpawnedSubsystem<E>;
}

A trait that describes the Subsystems that can run on the Overseer.

It is generic over the message type circulating in the system. The idea that we want some type containing persistent state that can spawn actually running subsystems when asked.

Required methods

fn start(self, ctx: Ctx) -> SpawnedSubsystem<E>

Start this Subsystem and return SpawnedSubsystem.

Implementors

impl<Context> Subsystem<Context, SubsystemError> for DummySubsystem where
    Context: SubsystemContext<Signal = OverseerSignal, Error = SubsystemError, AllMessages = AllMessages>,
