fn request_justification(&self, hash: &B::Hash, number: NumberFor<B>)

Request a justification for the given block from the network.

On success, the justification will be passed to the import queue that was part at initialization as part of the configuration.

source§

fn clear_justification_requests(&self)

Clear all pending justification requests.
source§

impl<B: BlockT> Link<B> for SyncingService<B>

Batch of blocks imported, with or without error.
source§

fn justification_imported( &self, who: PeerId, hash: &B::Hash, number: NumberFor<B>, success: bool, )

impl<B: BlockT> NetworkBlock<<B as Block>::Hash, <<B as Block>::Header as Header>::Number> for SyncingService<B>

source§

fn announce_block(&self, hash: B::Hash, data: Option<Vec<u8>>)

source§

fn new_best_block_imported(&self, hash: B::Hash, number: NumberFor<B>)

source§

impl<B: BlockT + 'static> NetworkSyncForkRequest<<B as Block>::Hash, <<B as Block>::Header as Header>::Number> for SyncingService<B>

source§

fn set_sync_fork_request( &self, peers: Vec<PeerId>, hash: B::Hash, number: NumberFor<B>, )

Configure an explicit fork sync request.

Note that this function should not be used for recent blocks. Sync should be able to download all the recent forks normally. set_sync_fork_request should only be used if external code detects that there’s a stale fork missing.

Passing empty peers set effectively removes the sync request.
