Optimism Payload Attributes

Fields

payload_attributes: PayloadAttributes

The payload attributes

transactions: Option<Vec<Bytes>>

Transactions is a field for rollups: the transactions list is forced into the block

no_tx_pool: Option<bool>

If true, the no transactions are taken out of the tx-pool, only transactions from the above Transactions list will be included.

gas_limit: Option<u64>

If set, this sets the exact gas limit the block produced with.

eip_1559_params: Option<FixedBytes<8>>

If set, this sets the EIP-1559 parameters for the block.

Prior to Holocene activation, this field should always be None.

Implementations

impl OpPayloadAttributes

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

Encodes the eip1559 parameters for the payload.

pub fn decode_eip_1559_params(&self) -> Option<(u32, u32)>

Extracts the Holocene 1599 parameters from the encoded form: https://github.com/ethereum-optimism/specs/blob/main/specs/protocol/holocene/exec-engine.md#eip1559params-encoding

Returns (elasticity, denominator)

Trait Implementations

impl Clone for OpPayloadAttributes

fn clone(&self) -> OpPayloadAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpPayloadAttributes

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

Formats the value using the given formatter.

impl<Provider, EvmConfig> DebugExecutionWitnessApiServer<OpPayloadAttributes> for OpDebugWitnessApi<Provider, EvmConfig>

where Provider: StateProviderFactory + ChainSpecProvider<ChainSpec = OpChainSpec> + Clone + 'static + BlockReaderIdExt<Header = Header>, EvmConfig: ConfigureEvm<Header = Header, Transaction = TransactionSigned> + 'static,

fn execute_payload<'life0, 'async_trait>( &'life0 self, parent_block_hash: FixedBytes<32>, attributes: OpPayloadAttributes, ) -> Pin<Box<dyn Future<Output = Result<ExecutionWitness, ErrorObject<'static>>> + Send + 'async_trait>>

where 'life0: 'async_trait, OpDebugWitnessApi<Provider, EvmConfig>: 'async_trait,

The debug_executePayload method allows for re-execution of a group of transactions with the purpose of generating an execution witness. The witness comprises of a map of all hashed trie nodes to their preimages that were required during the execution of the block, including during state root recomputation.

fn into_rpc(self) -> RpcModule<Self>

where Attributes: Send + Sync + 'static + DeserializeOwned,

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.

impl Default for OpPayloadAttributes

fn default() -> OpPayloadAttributes

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OpPayloadAttributes

fn deserialize<__D>( __deserializer: __D, ) -> Result<OpPayloadAttributes, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for OpPayloadAttributes

fn eq(&self, other: &OpPayloadAttributes) -> 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 PayloadAttributes for OpPayloadAttributes

Available on crate feature op only.

fn timestamp(&self) -> u64

Returns the timestamp to be used in the payload job.

fn withdrawals(&self) -> Option<&Vec<Withdrawal>>

Returns the withdrawals for the given payload attributes.

fn parent_beacon_block_root(&self) -> Option<FixedBytes<32>>

Return the parent beacon block root for the payload attributes.

impl Serialize for OpPayloadAttributes

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for OpPayloadAttributes

impl StructuralPartialEq for OpPayloadAttributes

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
