Optimism Payload Builder Attributes

Fields

payload_attributes: EthPayloadBuilderAttributes

Inner ethereum payload builder attributes

no_tx_pool: bool

NoTxPool option for the generated payload

transactions: Vec<WithEncoded<T>>

Decoded transactions and the original EIP-2718 encoded bytes as received in the payload attributes.

gas_limit: Option<u64>

The gas limit for the generated payload

eip_1559_params: Option<B64>

EIP-1559 parameters for the generated payload

min_base_fee: Option<u64>

Min base fee for the generated payload (only available post-Jovian)

Implementations

impl<T> OpPayloadBuilderAttributes<T>

pub fn get_holocene_extra_data( &self, default_base_fee_params: BaseFeeParams, ) -> Result<Bytes, EIP1559ParamError>

Extracts the extra data parameters post-Holocene hardfork. In Holocene, those parameters are the EIP-1559 base fee parameters.

pub fn get_jovian_extra_data( &self, default_base_fee_params: BaseFeeParams, ) -> Result<Bytes, EIP1559ParamError>

Extracts the extra data parameters post-Jovian hardfork. Those parameters are the EIP-1559 parameters from Holocene and the minimum base fee.

Trait Implementations

impl<H, T, ChainSpec> BuildNextEnv<OpPayloadBuilderAttributes<T>, H, ChainSpec> for OpNextBlockEnvAttributes

where H: BlockHeader, T: SignedTransaction, ChainSpec: EthChainSpec + OpHardforks,

fn build_next_env( attributes: &OpPayloadBuilderAttributes<T>, parent: &SealedHeader<H>, chain_spec: &ChainSpec, ) -> Result<Self, PayloadBuilderError>

Builds the EVM environment for the next block from the given payload attributes.

impl<T: Clone> Clone for OpPayloadBuilderAttributes<T>

fn clone(&self) -> OpPayloadBuilderAttributes<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for OpPayloadBuilderAttributes<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for OpPayloadBuilderAttributes<T>

fn default() -> Self

Returns the “default value” for a type.

impl<OpTransactionSigned> From<EthPayloadBuilderAttributes> for OpPayloadBuilderAttributes<OpTransactionSigned>

fn from(value: EthPayloadBuilderAttributes) -> Self

Converts to this type from the input type.

impl<T: SignedTransaction> OpAttributes for OpPayloadBuilderAttributes<T>

type Transaction = T

Primitive transaction type.

fn no_tx_pool(&self) -> bool

Whether to use the transaction pool for the payload.

fn sequencer_transactions(&self) -> &[WithEncoded<Self::Transaction>]

Sequencer transactions to include in the payload.

impl<T: PartialEq> PartialEq for OpPayloadBuilderAttributes<T>

fn eq(&self, other: &OpPayloadBuilderAttributes<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Decodable2718 + Send + Sync + Debug + Unpin + 'static> PayloadBuilderAttributes for OpPayloadBuilderAttributes<T>

fn try_new( parent: B256, attributes: OpPayloadAttributes, version: u8, ) -> Result<Self, Self::Error>

Creates a new payload builder for the given parent block and the attributes.

Derives the unique [PayloadId] for the given parent and attributes

type RpcPayloadAttributes = OpPayloadAttributes

The external payload attributes format this type can be constructed from.

type Error = Error

The error type used in PayloadBuilderAttributes::try_new.

fn payload_id(&self) -> PayloadId

Returns the unique identifier for this payload build job.

fn parent(&self) -> B256

Returns the hash of the parent block this payload builds on.

fn timestamp(&self) -> u64

Returns the timestamp to be used in the payload’s header.

fn parent_beacon_block_root(&self) -> Option<B256>

Returns the beacon chain block root from the parent block.

fn suggested_fee_recipient(&self) -> Address

Returns the address that should receive transaction fees.

fn prev_randao(&self) -> B256

Returns the randomness value for this block.

fn withdrawals(&self) -> &Withdrawals

Returns the list of withdrawals to be processed in this block.
