Basic attributes required to initiate payload construction.

Defines minimal parameters needed to build a new execution payload. Implementations must be serializable for transmission.

Required Methods

fn payload_id(&self, parent_hash: &FixedBytes<32>) -> PayloadId

Computes the unique identifier for this payload build job.

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.

Some for post-Shanghai blocks, None for earlier blocks.

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

Returns the parent beacon block root.

Some for post-merge blocks, None for pre-merge blocks.

fn slot_number(&self) -> Option<u64>

Returns the slot number for the new payload.

Some for post-Amsterdam blocks, None for earlier blocks.

Provided Methods

fn target_gas_limit(&self) -> Option<u64>

Returns the target gas limit for the new payload.

Some for payload attributes that specify the desired gas limit, None if the builder should use its configured target.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
