fn transaction_id(&self, tx_hash: TxHash) -> ProviderResult<Option<TxNumber>>

Get internal transaction identifier by transaction hash.

fn transaction_by_id( &self, id: TxNumber, ) -> ProviderResult<Option<Self::Transaction>>

Get transaction by id, computes hash every time so more expensive.

fn transaction_by_id_unhashed( &self, id: TxNumber, ) -> ProviderResult<Option<Self::Transaction>>

Get transaction by id without computing the hash.

fn transaction_by_hash( &self, hash: TxHash, ) -> ProviderResult<Option<Self::Transaction>>

Get transaction by transaction hash.

fn transaction_by_hash_with_meta( &self, tx_hash: TxHash, ) -> ProviderResult<Option<(Self::Transaction, TransactionMeta)>>

Get transaction by transaction hash and additional metadata of the block the transaction was mined in

fn transaction_block(&self, id: TxNumber) -> ProviderResult<Option<BlockNumber>>

Get transaction block number

fn transactions_by_block( &self, id: BlockHashOrNumber, ) -> ProviderResult<Option<Vec<Self::Transaction>>>

Get transactions by block id.

fn transactions_by_block_range( &self, range: impl RangeBounds<BlockNumber>, ) -> ProviderResult<Vec<Vec<Self::Transaction>>>

Get transactions by block range.

fn transactions_by_tx_range( &self, range: impl RangeBounds<TxNumber>, ) -> ProviderResult<Vec<Self::Transaction>>

Get transactions by tx range.

fn senders_by_tx_range( &self, range: impl RangeBounds<TxNumber>, ) -> ProviderResult<Vec<Address>>

Get Senders from a tx range.

fn transaction_sender(&self, id: TxNumber) -> ProviderResult<Option<Address>>

impl<TX: DbTx + 'static, N: NodeTypesForProvider> TransactionsProviderExt for DatabaseProvider<TX, N>

fn transaction_hashes_by_range( &self, tx_range: Range<TxNumber>, ) -> ProviderResult<Vec<(TxHash, TxNumber)>>

Recovers transaction hashes by walking through Transactions table and calculating them in a parallel manner. Returned unsorted.

fn transaction_range_by_block_range( &self, block_range: RangeInclusive<u64>, ) -> Result<RangeInclusive<u64>, ProviderError>

Get transactions range by block range.

impl<TX: DbTx + 'static, N: NodeTypes> TryIntoHistoricalStateProvider for DatabaseProvider<TX, N>

fn try_into_history_at_block( self, block_number: BlockNumber, ) -> ProviderResult<StateProviderBox>

Returns a historical StateProvider indexed by the given historic block number.

impl<TX: DbTx + 'static, N: NodeTypes<ChainSpec: EthereumHardforks>> WithdrawalsProvider for DatabaseProvider<TX, N>

fn withdrawals_by_block( &self, id: BlockHashOrNumber, timestamp: u64, ) -> ProviderResult<Option<Withdrawals>>
