Expand description

Loads a pending block from database.

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

Required Methods§

fn provider( &self, ) -> impl BlockReaderIdExt + EvmEnvProvider + ChainSpecProvider<ChainSpec = ChainSpec> + StateProviderFactory

Returns a handle for reading data from disk.

Data access in default (L1) trait method implementations.

fn pool(&self) -> impl TransactionPool

Returns a handle for reading data from transaction pool.

Data access in default (L1) trait method implementations.

fn pending_block(&self) -> &Mutex<Option<PendingBlock>>

Returns a handle to the pending block.

Data access in default (L1) trait method implementations.

fn evm_config(&self) -> &impl ConfigureEvm

Returns a handle for reading evm config.

Data access in default (L1) trait method implementations.

Provided Methods§

fn pending_block_env_and_cfg(&self) -> Result<PendingBlockEnv, Self::Error>

Configures the CfgEnvWithHandlerCfg and BlockEnv for the pending block

If no pending block is available, this will derive it from the latest block

fn local_pending_block( &self, ) -> impl Future<Output = Result<Option<(SealedBlockWithSenders, Vec<Receipt>)>, Self::Error>> + Send
where Self: SpawnBlocking,

Returns the locally built pending block

fn assemble_receipt( &self, tx: &TransactionSignedEcRecovered, result: ExecutionResult, cumulative_gas_used: u64, ) -> Receipt

Assembles a Receipt for a transaction, based on its ExecutionResult.

fn receipts_root( &self, _block_env: &BlockEnv, execution_outcome: &ExecutionOutcome, block_number: u64, ) -> FixedBytes<32>

Calculates receipts root in block building.

Panics if block is not in the [ExecutionOutcome]’s block range.

fn build_block( &self, env: PendingBlockEnv, ) -> Result<(SealedBlockWithSenders, Vec<Receipt>), Self::Error>
where EthApiError: From<ProviderError>,

Builds a pending block using the configured provider and pool.

If the origin is the actual pending block, the block is built with withdrawals.

After Cancun, if the origin is the actual pending block, the block includes the EIP-4788 pre block contract call using the parent beacon block root received from the CL.

Object Safety§

This trait is not object safe.
