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>>

Get transaction sender.

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> TrieReader for DatabaseProvider<TX, N>

fn trie_reverts(&self, from: BlockNumber) -> ProviderResult<TrieUpdatesSorted>

Returns the [TrieUpdatesSorted] for reverting the trie database to its state prior to the given block and onwards having been processed.

fn get_block_trie_updates( &self, block_number: BlockNumber, ) -> ProviderResult<TrieUpdatesSorted>

Returns the trie updates that were applied by the specified block.

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

fn write_trie_updates_sorted( &self, trie_updates: &TrieUpdatesSorted, ) -> ProviderResult<usize>

Writes trie updates to the database with already sorted updates.

Returns the number of entries modified.

fn write_trie_changesets( &self, block_number: BlockNumber, trie_updates: &TrieUpdatesSorted, updates_overlay: Option<&TrieUpdatesSorted>, ) -> ProviderResult<usize>

Records the current values of all trie nodes which will be updated using the TrieUpdates into the trie changesets tables.

The intended usage of this method is to call it prior to calling write_trie_updates with the same TrieUpdates.

Returns the number of keys written.

fn clear_trie_changesets(&self) -> ProviderResult<()>

Clears contents of trie changesets completely

fn clear_trie_changesets_from(&self, from: BlockNumber) -> ProviderResult<()>

Clears contents of trie changesets starting from the given block number (inclusive) onwards.

fn write_trie_updates( &self, trie_updates: TrieUpdates, ) -> Result<usize, ProviderError>

Writes trie updates to the database.

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.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
