A service that verifies downloaded transactions.

state: ZS

A service that manages cached blockchain state.

pending: FuturesUnordered<JoinHandle<Result<VerifiedUnminedTx, (TransactionDownloadVerifyError, UnminedTxId)>>>

source

pub fn new(network: ZN, verifier: ZV, state: ZS) -> Self

Initialize a new download stream with the provided services.

network is used to download transactions. verifier is used to verify transactions. state is used to check if transactions are already in the state.

The Downloads stream is agnostic to the network policy, so retry and timeout limits should be applied to the network service passed into this constructor.

source

pub fn download_if_needed_and_verify(
&mut self,
gossiped_tx: Gossip
) -> Result<(), MempoolError>

Queue a transaction for download (if needed) and verification.

Returns the action taken in response to the queue request.

source

pub fn cancel(&mut self, mined_ids: &HashSet<Hash>)

Cancel download/verification tasks of transactions with the given transaction hash (see UnminedTxId::mined_id).

source

pub fn cancel_all(&mut self)

Cancel all running tasks and reset the downloader state.

source

pub fn in_flight(&self) -> usize

Get the number of currently in-flight download tasks.

source

async fn transaction_in_state(
state: &mut ZS,
txid: UnminedTxId
) -> Result<(), TransactionDownloadVerifyError>

Check if transaction is already in the state.
