This structure contains the attributes required to initiate a payload build process in the context of an engine_forkchoiceUpdated call.

Fields

timestamp: u64

Value for the timestamp field of the new payload

prev_randao: FixedBytes<32>

Value for the prevRandao field of the new payload

suggested_fee_recipient: Address

Suggested value for the feeRecipient field of the new payload

withdrawals: Option<Vec<Withdrawal>>

Array of [Withdrawal] enabled with V2 See https://github.com/ethereum/execution-apis/blob/6452a6b194d7db269bf1dbd087a267251d3cc7f8/src/engine/shanghai.md#payloadattributesv2

parent_beacon_block_root: Option<FixedBytes<32>>

Root of the parent beacon block enabled with V3.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for PayloadAttributes

fn arbitrary( u: &mut Unstructured<'arbitrary>, ) -> Result<PayloadAttributes, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest( u: Unstructured<'arbitrary>, ) -> Result<PayloadAttributes, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for PayloadAttributes

fn clone(&self) -> PayloadAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadAttributes

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

Formats the value using the given formatter.

impl Default for PayloadAttributes

fn default() -> PayloadAttributes

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PayloadAttributes

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PayloadAttributes

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

fn timestamp(&self) -> u64

Returns the timestamp for the new payload.

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

Returns the withdrawals to be included in the payload.

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

Returns the parent beacon block root.

impl Serialize for PayloadAttributes

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 PayloadAttributes

impl StructuralPartialEq for PayloadAttributes

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.
