pub struct DatabaseTransaction { /* private fields */ }

Methods from Deref<Target = Database>

pub fn latest_height(&self) -> StorageResult<BlockHeight>

pub fn get_current_block( &self ) -> StorageResult<Option<Cow<'_, CompressedBlock>>>

pub fn get_contract_config_by_id( &self, contract_id: ContractId ) -> StorageResult<ContractConfig>

pub fn contract_balances( &self, contract: ContractId, start_asset: Option<AssetId>, direction: Option<IterDirection> ) -> impl Iterator<Item = DatabaseResult<(AssetId, Word)>> + '_

pub fn get_contract_config(&self) -> StorageResult<Option<Vec<ContractConfig>>>

pub fn owned_message_ids( &self, owner: &Address, start_message_id: Option<Nonce>, direction: Option<IterDirection> ) -> impl Iterator<Item = DatabaseResult<Nonce>> + '_

pub fn get_message_config(&self) -> StorageResult<Option<Vec<MessageConfig>>>

pub fn is_message_spent(&self, id: &Nonce) -> StorageResult<bool>

pub fn get_sealed_block_by_id( &self, block_id: &BlockId ) -> StorageResult<Option<SealedBlock>>

pub fn get_sealed_block_by_height( &self, height: &BlockHeight ) -> StorageResult<Option<SealedBlock>>

Returns SealedBlock by height. Reusable across different trait implementations

pub fn get_genesis(&self) -> StorageResult<Genesis>

pub fn get_sealed_block_header_by_height( &self, height: &BlockHeight ) -> StorageResult<Option<SealedBlockHeader>>

pub fn get_sealed_block_header( &self, block_id: &BlockId ) -> StorageResult<Option<SealedBlockHeader>>

pub fn get_transactions_on_block( &self, block_id: &BlockId ) -> StorageResult<Option<Vec<Transaction>>>

pub fn owned_coins_ids( &self, owner: &Address, start_coin: Option<UtxoId>, direction: Option<IterDirection> ) -> impl Iterator<Item = DatabaseResult<UtxoId>> + '_

pub fn coin(&self, utxo_id: &UtxoId) -> StorageResult<CompressedCoin>

pub fn get_coin_config(&self) -> DatabaseResult<Option<Vec<CoinConfig>>>

pub fn init(&self, config: &ChainConfig) -> DatabaseResult<()>

Ensures the database is initialized and that the database version is correct

pub fn get_chain_name(&self) -> DatabaseResult<Option<String>>

pub fn all_transactions( &self, start: Option<&Bytes32>, direction: Option<IterDirection> ) -> impl Iterator<Item = DatabaseResult<Transaction>> + '_

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

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 ) -> DatabaseResult<Option<Bytes32>>

pub fn update_tx_status( &self, id: &Bytes32, status: TransactionStatus ) -> DatabaseResult<Option<TransactionStatus>>

pub fn get_tx_status( &self, id: &Bytes32 ) -> DatabaseResult<Option<TransactionStatus>>

pub fn transaction(&self) -> DatabaseTransaction

Trait Implementations
