Trait reth_node_builder::PayloadAttributes

pub trait PayloadAttributes: DeserializeOwned + Serialize + Debug + Clone + Send + Sync + 'static {
    // Required methods
    fn timestamp(&self) -> u64;
    fn withdrawals(&self) -> Option<&Vec<Withdrawal>>;
    fn parent_beacon_block_root(&self) -> Option<FixedBytes<32>>;

}

The execution payload attribute type the CL node emits via the engine API. This trait should be implemented by types that could be used to spawn a payload job.

This type is emitted as part of the forkchoiceUpdated call

Required Methods

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.

fn ensure_well_formed_attributes( &self, chain_spec: &ChainSpec, version: EngineApiMessageVersion ) -> Result<(), EngineObjectValidationError>

Ensures that the payload attributes are valid for the given [ChainSpec] and EngineApiMessageVersion.

Object Safety

This trait is not object safe.
