Implementations

impl TxStoreOverlay

pub fn new(overlay: &SledDbOverlayPtr) -> Result<Self>

pub fn insert( &self, transactions: &[Transaction], ) -> Result<Vec<TransactionHash>>

Insert a slice of Transaction into the overlay’s main tree. The transactions are hashed with BLAKE3 and this hash is used as the key, while the value is the serialized Transaction itself. On success, the function returns the transaction hashes in the same order as the input transactions.

pub fn insert_location( &self, txs_hashes: &[TransactionHash], block_height: u32, ) -> Result<()>

Insert a slice of TransactionHash into the overlay’s location tree. The location tuple is built using the index of each transaction hash in the slice, along with the provided block height

pub fn get( &self, tx_hashes: &[TransactionHash], strict: bool, ) -> Result<Vec<Option<Transaction>>>

Fetch given tx hashes from the overlay’s main tree. The resulting vector contains Option, which is Some if the tx was found in the overlay, and otherwise it is None, if it has not. The second parameter is a boolean which tells the function to fail in case at least one tx was not found.

pub fn get_raw(&self, tx_hash: &[u8; 32]) -> Result<Option<Vec<u8>>>

Fetch given tx hash from the overlay’s main tree. This function uses raw bytes as input and doesn’t deserialize the retrieved value. The resulting vector contains Option, which is Some if the tx was found in the overlay, and otherwise it is None, if it has not.

pub fn get_location_raw(&self, tx_hash: &[u8; 32]) -> Result<Option<Vec<u8>>>

Fetch given tx hash location from the overlay’s location tree. This function uses raw bytes as input and doesn’t deserialize the retrieved value. The resulting vector contains Option, which is Some if the location was found in the overlay, and otherwise it is None, if it has not.
