Expand description

The transaction pool [tower::Service] read request type.

§include_sensitive_txs

This field exists in many requests. If this is true, the request will include private (local) transactions in the response.

Variants§

§

TxBlob(TransactionHash)

Get the blob (raw bytes) of a transaction with the given hash.

§

TxVerificationData(TransactionHash)

Get the [TransactionVerificationData] of a transaction in the tx pool.

§

FilterKnownTxBlobHashes(HashSet<TransactionBlobHash>)

Filter (remove) all known transactions from the set.

The hash is not the transaction hash, it is the hash of the serialized tx-blob.

§

TxsForBlock(Vec<TransactionHash>)

Get some transactions for an incoming block.

§

Backlog

Get information on all transactions in the pool.

§

Size

Get the number of transactions in the pool.

Fields

§include_sensitive_txs: bool
§

PoolInfo

Get general information on the txpool.

Fields

§include_sensitive_txs: bool
§max_tx_count: usize

The maximum amount of transactions to retrieve.

§start_time: Option<NonZero<usize>>

Fetch transactions that start from this time.

None means all transactions.

§

TxsByHash

Get transactions by their hashes.

Fields

§tx_hashes: Vec<[u8; 32]>
§include_sensitive_txs: bool
§

KeyImagesSpent

Check if any individual key images of a set exist in the txpool.

Fields

§key_images: HashSet<[u8; 32]>
§include_sensitive_txs: bool
§

KeyImagesSpentVec

Same as TxpoolReadRequest::KeyImagesSpent but with a Vec.

The response will be in the same order as the request.

Fields

§key_images: Vec<[u8; 32]>
§include_sensitive_txs: bool
§

Pool

Get txpool info.

Fields

§include_sensitive_txs: bool
§

PoolStats

Get txpool stats.

Fields

§include_sensitive_txs: bool
§

AllHashes

Get the hashes of all transaction in the pool.

Fields

§include_sensitive_txs: bool
