Implementations

impl DatabaseTransaction

pub fn all_transactions(

pub fn owned_transactions(
    &self,
    owner: &Address,
    start: Option<&OwnedTransactionIndexCursor>,
    direction: Option<IterDirection>
) -> impl Iterator<Item = Result<(OwnedTransactionIndexCursor, Bytes32 ), Error>> + '_

Iterates over a KV mapping of [address + block height + tx idx] => transaction id. This allows for efficient lookup of transaction ids associated with an address, sorted by block age and ordering within a block. The cursor tracks the [block height + tx idx] for pagination purposes.

pub fn record_tx_id_owner(
    &self,
    owner: &Address,
    block_height: BlockHeight,
    tx_idx: TransactionIndex,
    tx_id: &Bytes32
) -> Result<Option<Bytes32>, Error>

pub fn update_tx_status(
    &self,
    tx_id: &Bytes32,
    status: TransactionStatus
) -> Result<Option<TransactionStatus>, Error>

pub fn get_tx_status(
&self,
tx_id: &Bytes32
) -> Result<Option<TransactionStatus>, Error>

pub fn transaction(&self) -> DatabaseTransaction
