}

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 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<B256>

Returns the parent beacon block root.

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
