Required Methods

fn service(&self) -> Box<dyn ImportQueueService<B>>

Get a copy of the handle to ImportQueueService.

fn service_ref(&mut self) -> &mut dyn ImportQueueService<B>

Get a reference to the handle to ImportQueueService.

fn poll_actions(&mut self, cx: &mut Context<'_>, link: &mut dyn Link<B>)

This method should behave in a way similar to Future::poll. It can register the current task and notify later when more actions are ready to be polled. To continue the comparison, it is as if this method always returned Poll::Pending.

fn run<'async_trait>( self, link: Box<dyn Link<B>> ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait,

Start asynchronous runner for import queue.

Takes an object implementing Link which allows the import queue to influence the synchronization process.
