Trait Implementations§

fn clone(&self) -> SyncingService

Returns a copy of the value. Read more

1.0.0 · source§

fn clone_from(&mut self, source: &Self)

impl<B: BlockT> JustificationSyncLink for SyncingService

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

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.

fn clear_justification_requests(&self)

Clear all pending justification requests.

impl<B: BlockT> Link for SyncingService

fn blocks_processed( &mut self, imported: usize, count: usize, results: Vec<(Result<BlockImportStatus<NumberFor>, BlockImportError>, B::Hash)> )

Batch of blocks imported, with or without error.

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

Justification import result.

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

Request a justification for the given block.

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

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

Inform the network service about new best imported block.

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

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.
