}

Loads a transaction from database.

Behaviour shared by several eth_ RPC methods, not exclusive to eth_ transactions RPC methods.

Required Associated Types

type Pool: TransactionPool

Transaction pool with pending transactions. [TransactionPool::Transaction] is the supported transaction type.

Required Methods

fn provider(&self) -> impl TransactionsProvider

Returns a handle for reading data from disk.

Data access in default (L1) trait method implementations.

fn cache(&self) -> &EthStateCache

Returns a handle for reading data from memory.

Data access in default (L1) trait method implementations.

fn pool(&self) -> &Self::Pool

Returns a handle for reading data from pool.

Data access in default (L1) trait method implementations.

Provided Methods

fn transaction_by_hash( &self, hash: FixedBytes<32>, ) -> impl Future<Output = Result<Option<TransactionSource>, Self::Error>> + Send

Returns the transaction by hash.

Checks the pool and state.

Returns Ok(None) if no matching transaction was found.

fn transaction_by_hash_at( &self, transaction_hash: FixedBytes<32>, ) -> impl Future<Output = Result<Option<(TransactionSource, BlockId)>, Self::Error>> + Send

Returns the transaction by including its corresponding BlockId.

Note: this supports pending transactions

fn transaction_and_block( &self, hash: FixedBytes<32>, ) -> impl Future<Output = Result<Option<(TransactionSource, SealedBlockWithSenders)>, Self::Error>> + Send

Fetches the transaction and the transaction’s block
