Trait sc_service::ImportQueue

pub trait ImportQueue<B>: Send where
    B: Block, {
    fn import_blocks(
        &mut self, 
        origin: BlockOrigin, 
        blocks: Vec<IncomingBlock<B>, Global>
    );
    fn import_justifications(
        &mut self, 
        who: PeerId, 
        hash: <B as Block>::Hash, 
        number: <<B as Block>::Header as Header>::Number, 
        justifications: Justifications
    );
    fn poll_actions(&mut self, cx: &mut Context<'_>, link: &mut dyn Link<B>);
}

Blocks import queue API.

The import_* methods can be called in order to send elements for the import queue to verify. Afterwards, call poll_actions to determine how to respond to these elements.

Required methods

fn import_blocks(
    &mut self,
    origin: BlockOrigin,
    blocks: Vec<IncomingBlock<B>, Global>
)

Import bunch of blocks.

fn import_justifications(
    &mut self,
    who: PeerId,
    hash: <B as Block>::Hash,
    number: <<B as Block>::Header as Header>::Number,
    justifications: Justifications
)

Import block justifications.

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

Polls for actions to perform on the network.

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.
