}

SSZ container matching SszExecutionPayload at execution-specs 3c3b6f4af (#3248): a ProgressiveContainer(active_fields=[1; 19]) whose transaction, withdrawal and block-access-list fields are progressive lists.

HashTreeRoot is hand-written because libssz-derive has no progressive support; encode/decode still derive, since nothing progressive changes the wire layout (ProgressiveList delegates both to Vec<T>).

Fields

parent_hash: [u8; 32]

fee_recipient: Bytes20

state_root: [u8; 32]

receipts_root: [u8; 32]

logs_bloom: LogsBloom

prev_randao: [u8; 32]

block_number: u64

gas_limit: u64

gas_used: u64

timestamp: u64

extra_data: SszList<u8, MAX_EXTRA_DATA_BYTES>

base_fee_per_gas: [u8; 32]

base_fee_per_gas encoded as a 256-bit unsigned integer (little-endian).

block_hash: [u8; 32]

transactions: ProgressiveList<ProgressiveList<u8>>

withdrawals: ProgressiveList<Withdrawal>

blob_gas_used: u64

excess_blob_gas: u64

block_access_list: ProgressiveList<u8>

EIP-7928 block-level access list (full serialized BAL bytes).

slot_number: u64

EIP-7843 slot number (Amsterdam+). Last field, matching the execution-specs ExecutionPayloadV4 layout so the native path is byte-compatible with the spec-current payload. Provided by the L2 producer and carried to L1.

Trait Implementations

impl Clone for ExecutionPayload

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionPayload

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

Formats the value using the given formatter.

impl Eq for ExecutionPayload

impl HashTreeRoot for ExecutionPayload

fn hash_tree_root(&self, hasher: &impl Sha256Hasher) -> Node

fn is_basic_type() -> bool

where Self: Sized,

Returns true for SSZ basic types (bool, uN, byte arrays). Composite types (containers, vectors, lists) return false. Used by Vector/List HTR to decide between packing and per-element hashing.

impl PartialEq for ExecutionPayload

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl SszDecode for ExecutionPayload

fn is_fixed_size() -> bool

Returns true if this type has a fixed SSZ size.

fn fixed_size() -> usize

Returns the fixed size in bytes. Only meaningful when is_fixed_size() is true.

fn from_ssz_bytes(bytes: &[u8]) -> Result<Self, DecodeError>

Decode from SSZ bytes.

fn ssz_decode_fixed_vec(bytes: &[u8]) -> Result<Vec<Self>, DecodeError>

Bulk-decode a byte buffer into a Vec of fixed-size items.

impl SszEncode for ExecutionPayload

fn is_fixed_size() -> bool

Returns true if this type has a fixed SSZ size.

fn fixed_size() -> usize

Returns the fixed size in bytes. Only meaningful when is_fixed_size() is true.

fn encoded_len(&self) -> usize

Returns the encoded length in bytes for this value.

fn ssz_append(&self, buf: &mut Vec<u8>)

Appends the SSZ encoding of self to buf.

fn ssz_append_fixed_slice(items: &[Self], buf: &mut Vec<u8>)

where Self: Sized,

Bulk-append a slice of fixed-size items to buf.

fn to_ssz(&self) -> Vec<u8>

Returns the SSZ encoding as a new Vec<u8>.
