    },
}

A response to a mempool service request.

Responses can read the current set of mempool transactions, check the queued status of transactions to be downloaded and verified, or confirm that the mempool has been checked for newly verified transactions.

Variants

TransactionIds(HashSet<UnminedTxId>)

Returns all UnminedTxIds from the mempool.

Transactions(Vec<UnminedTx>)

Returns matching UnminedTx from the mempool.

Since the Request::TransactionsById request is unique, the response transactions are also unique. The same applies to Request::TransactionsByMinedId requests, since the mempool does not allow different transactions with different mined IDs.

UnspentOutput(Output)

Response to Request::AwaitOutput with the transparent output

TransactionWithDeps

Response to Request::TransactionWithDepsByMinedId.

Fields

transaction: VerifiedUnminedTx

The queried transaction

dependencies: HashSet<Hash>

A list of dependencies of the queried transaction.

FullTransactions

Returns all VerifiedUnminedTx in the mempool.

Fields

transactions: Vec<VerifiedUnminedTx>

All VerifiedUnminedTxs in the mempool

transaction_dependencies: TransactionDependencies

All transaction dependencies in the mempool

last_seen_tip_hash: Hash

Last seen chain tip hash by mempool service

RejectedTransactionIds(HashSet<UnminedTxId>)

Returns matching cached rejected UnminedTxIds from the mempool,

Queued(Vec<Result<Receiver<Result<(), BoxError>>, BoxError>>)

Returns a list of initial queue checks results and a oneshot receiver for awaiting download and/or verification results.

Each result matches the request at the corresponding vector index.

CheckedForVerifiedTransactions

Confirms that the mempool has checked for recently verified transactions.

QueueStats

Summary statistics for the mempool: count, total size, memory usage, and regtest info.

Fields

size: usize

Number of transactions currently in the mempool

bytes: usize

Total size in bytes of all transactions

usage: usize

Estimated memory usage in bytes

fully_notified: Option<bool>

Whether all transactions have been fully notified (regtest only)

Trait Implementations
