Fields

number: u64

The current L1 origin block number

time: u64

The current L1 origin block’s timestamp

base_fee: u64

The current L1 origin block’s basefee

block_hash: FixedBytes<32>

The current L1 origin block’s hash

sequence_number: u64

The current sequence number

batcher_address: Address

The address of the batch submitter

blob_base_fee: u128

The current blob base fee on L1

blob_base_fee_scalar: u32

The fee scalar for L1 blobspace data

base_fee_scalar: u32

The fee scalar for L1 data

empty_scalars: bool

Indicates that the scalars are empty. This is an edge case where the first block in ecotone has no scalars, so the bedrock tx l1 cost function needs to be used.

l1_fee_overhead: Uint<256, 4>

The l1 fee overhead used along with the empty_scalars field for the bedrock tx l1 cost function.

This field is deprecated in the Ecotone Hardfork.

Implementations

impl L1BlockInfoEcotone

pub const L1_SCALAR: u8 = 1u8

The type byte identifier for the L1 scalar format in Ecotone.

pub const L1_INFO_TX_LEN: usize = 164usize

The length of an L1 info transaction in Ecotone.

pub const L1_INFO_TX_SELECTOR: [u8; 4]

The 4 byte selector of “setL1BlockValuesEcotone()”

pub fn encode_calldata(&self) -> Bytes

Encodes the L1BlockInfoEcotone object into Ethereum transaction calldata.

pub fn decode_calldata(r: &[u8]) -> Result<L1BlockInfoEcotone, DecodeError>

Decodes the L1BlockInfoEcotone object from ethereum transaction calldata.

Trait Implementations

impl Clone for L1BlockInfoEcotone

fn clone(&self) -> L1BlockInfoEcotone

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for L1BlockInfoEcotone

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

Formats the value using the given formatter.

impl Default for L1BlockInfoEcotone

fn default() -> L1BlockInfoEcotone

Returns the “default value” for a type.

impl Hash for L1BlockInfoEcotone

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for L1BlockInfoEcotone

fn eq(&self, other: &L1BlockInfoEcotone) -> 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.
