Struct OpPayloadAttributes

pub struct OpPayloadAttributes {
    pub payload_attributes: PayloadAttributes,
    pub transactions: Option<Vec<Bytes>>,

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<B64>

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>

Extracts 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

Formats the value using the given formatter.

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<Self, __D::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 Serialize for OpPayloadAttributes

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
