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>>)

Import bunch of blocks.

fn import_justification(
    &mut self,
    who: PeerId,
    hash: <B as Block>::Hash,
    number: <<B as Block>::Header as Header>::Number,
    justification: Vec<u8>
)

Import a block justification.

fn import_finality_proof(
    &mut self,
    who: PeerId,
    hash: <B as Block>::Hash,
    number: <<B as Block>::Header as Header>::Number,
    finality_proof: Vec<u8>
)

Import block finality proof.

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.
