Struct Crawler 

Source 
pub struct Crawler<PeerSet, Mempool> {
    peer_set: Timeout<PeerSet>,
    mempool: Mempool,

Expand description

The mempool transaction crawler.

Fields§

§peer_set: Timeout<PeerSet>

The network peer set to crawl.

§mempool: Mempool

The mempool service that receives crawled transaction IDs.

§sync_status: SyncStatus

Allows checking if we are near the tip to enable/disable the mempool crawler.

§chain_tip_change: ChainTipChange

Notifies the crawler when the best chain tip height changes.

§debug_enable_at_height: Option<Height>

If the state’s best chain tip has reached this height, always enable the mempool crawler.

Implementations§

Source§

impl<PeerSet, Mempool> Crawler<PeerSet, Mempool>
where PeerSet: Service<Request, Response = Response, Error = BoxError> + Clone + Send + 'static, PeerSet::Future: Send, Mempool: Service<Request, Response = Response, Error = BoxError> + Send + 'static, Mempool::Future: Send,

Source

pub fn spawn( config: &Config, peer_set: PeerSet, mempool: Mempool, sync_status: SyncStatus, chain_tip_change: ChainTipChange, ) -> JoinHandle<Result<(), BoxError>>

Spawn an asynchronous task to run the mempool crawler.

Source

async fn wait_until_enabled_by_debug(&mut self) -> Result<(), RecvError>

Waits until the mempool crawler is enabled by a debug config option.

Returns an error if communication with the state is lost.

Source

async fn wait_until_enabled(&mut self) -> Result<(), RecvError>

Waits until the mempool crawler is enabled.

Returns an error if communication with the syncer or state is lost.

Source

pub async fn run(self) -> Result<(), BoxError>

Periodically crawl peers for transactions to include in the mempool.

Runs until the SyncStatus loses its connection to the chain syncer, which happens when Zebra is shutting down.

Source

async fn crawl_transactions(&mut self) -> Result<(), BoxError>

Crawl peers for transactions.

Concurrently request FANOUT peers for transactions to include in the mempool.

Source

async fn handle_response(&mut self, response: Response) -> Result<(), BoxError>

Handle a peer’s response to the crawler’s request for transactions.

Source

async fn queue_transactions( &mut self, transaction_ids: HashSet<UnminedTxId>, ) -> Result<(), BoxError>

Forward the crawled transactions IDs to the mempool transaction downloader.
