Member Function Documentation

virtual bool kagome::network::Synchronizer::hasIncompleteRequestOfStateSync ( ) const
pure virtual

Implemented in kagome::network::SynchronizerImpl.

virtual bool kagome::network::Synchronizer::syncByBlockHeader ( const primitives::BlockHeader &  header,
const libp2p::peer::PeerId &  peer_id,
SyncResultHandler &&  handler 
)
pure virtual

Try to load and apply block with header {

Parameters
block_header}from peer {
peer_id}.If provided block is the best after applying, {
handler}be called
Returns
true if sync is ran (peer is not busy)
Note
Is used for finish catching up if it possible, and start/continue than otherwise

Implemented in kagome::network::SynchronizerImpl.

virtual bool kagome::network::Synchronizer::syncByBlockInfo ( const primitives::BlockInfo &  block_info,
const libp2p::peer::PeerId &  peer_id,
SyncResultHandler &&  handler,
bool  subscribe_to_block 
)
pure virtual

Enqueues loading (and applying) blocks from peer {

Parameters
peer_id}since best common block up to provided {
block_info}.{
handler}will be called when this process is finished or failed
Returns
true if sync is ran (peer is not busy)
Note
Is used for start/continue catching up.

Implemented in kagome::network::SynchronizerImpl.

virtual void kagome::network::Synchronizer::syncMissingJustifications ( const libp2p::peer::PeerId &  peer_id,
primitives::BlockInfo  target_block,
std::optional< uint32_t >  limit,
SyncResultHandler &&  handler 
)
pure virtual

Tries to request block justifications from {

Parameters
peer_id}for {
target_block}or a range of blocks up to {
limit}count. Calls {
handler}when operation finishes

Implemented in kagome::network::SynchronizerImpl.

virtual void kagome::network::Synchronizer::syncState ( const libp2p::peer::PeerId &  peer_id,
const primitives::BlockInfo &  block,
SyncResultHandler &&  handler 
)
pure virtual

Implemented in kagome::network::SynchronizerImpl.
