Expand description
Syncing strategy that downloads and imports a recent state directly.
Implementations§
source§impl<B: BlockT> StateStrategy<B>
impl<B: BlockT> StateStrategy<B>
sourcepub const STRATEGY_KEY: StrategyKey = _
pub const STRATEGY_KEY: StrategyKey = _
Strategy key used by state sync.
sourcepub fn new<Client>(
client: Arc<Client>,
target_header: B::Header,
target_body: Option<Vec<B::Extrinsic>>,
target_justifications: Option<Justifications>,
skip_proof: bool,
initial_peers: impl Iterator<Item = (PeerId, NumberFor<B>)>,

) -> Self
pub fn new<Client>( client: Arc<Client>, target_header: B::Header, target_body: Option<Vec<B::Extrinsic>>, target_justifications: Option<Justifications>, skip_proof: bool, initial_peers: impl Iterator<Item = (PeerId, NumberFor<B>)>, protocol_name: ProtocolName, ) -> Self
Create a new instance.
sourcepub fn new_with_provider(
state_sync_provider: Box<dyn StateSyncProvider<B>>,
initial_peers: impl Iterator<Item = (PeerId, NumberFor<B>)>,
protocol_name: ProtocolName,
) -> Self
pub fn new_with_provider( state_sync_provider: Box<dyn StateSyncProvider<B>>, initial_peers: impl Iterator<Item = (PeerId, NumberFor<B>)>, protocol_name: ProtocolName, ) -> Self
Create a new instance with a custom state sync provider.
Note: In most cases, users should use StateStrategy::new
.
This method is intended for custom sync strategies and advanced use cases.
sourcepub fn add_peer(
&mut self,
peer_id: PeerId,
_best_hash: B::Hash,
best_number: NumberFor<B>,
)
pub fn add_peer( &mut self, peer_id: PeerId, _best_hash: B::Hash, best_number: NumberFor<B>, )
Notify that a new peer has connected.
sourcepub fn remove_peer(&mut self, peer_id: &PeerId)
pub fn remove_peer(&mut self, peer_id: &PeerId)
Notify that a peer has disconnected.
sourcepub fn on_validated_block_announce(
&mut self,
is_best: bool,
peer_id: PeerId,
announce: &BlockAnnounce<B::Header>,
) -> Option<(B::Hash, NumberFor<B>)>
pub fn on_validated_block_announce( &mut self, is_best: bool, peer_id: PeerId, announce: &BlockAnnounce<B::Header>, ) -> Option<(B::Hash, NumberFor<B>)>
Submit a validated block announcement.
Returns new best hash & best number of the peer if they are updated.
sourcepub fn on_state_response(&mut self, peer_id: &PeerId, response: Vec<u8>)
pub fn on_state_response(&mut self, peer_id: &PeerId, response: Vec<u8>)
Process state response.
sourcepub fn on_blocks_processed(
&mut self,
imported: usize,
count: usize,
results: Vec<(Result<BlockImportStatus<NumberFor<B>>, BlockImportError>, B::Hash)>,
)
pub fn on_blocks_processed( &mut self, imported: usize, count: usize, results: Vec<(Result<BlockImportStatus<NumberFor<B>>, BlockImportError>, B::Hash)>, )
A batch of blocks have been processed, with or without errors.
Normally this should be called when target block with state is imported.
sourcepub fn status(&self) -> SyncStatus<B>
pub fn status(&self) -> SyncStatus<B>
Returns the current sync status.
sourcepub fn actions(
&mut self,
network_service: &NetworkServiceHandle,
) -> impl Iterator<Item = SyncingAction<B>>
pub fn actions( &mut self, network_service: &NetworkServiceHandle, ) -> impl Iterator<Item = SyncingAction<B>>
Get actions that should be performed.
sourcepub fn is_succeeded(&self) -> bool
pub fn is_succeeded(&self) -> bool
Check if state sync has succeeded.
