What eth_getBlockByNumber and eth_getBlockByHash answer on Nitro.

Fields

number: u64

hash: B256

parent_hash: B256

timestamp: u64

Unix seconds.

gas_limit: u64

gas_used: u64

base_fee_per_gas: Option<U256>

miner: Address

The sequencer’s fee account, not a miner.

transactions: BlockTransactions

l1_block_number: u64

The parent chain’s block this one was sequenced at.

send_count: u64

How many messages to the parent chain had been sent by the end of this block: the size of the outbox’s tree.

send_root: B256

The root of the outbox’s tree after this block, what a confirmed assertion commits to.

mix_hash: B256

Nitro packs the send count, the parent block and ArbOS’s version into it.

Implementations

impl Block

pub fn arbos_version(&self) -> u64

ArbOS’s version when the block was made: the third eight bytes of its mix hash. ArbSys.arbOSVersion() answers it plus 55.

Trait Implementations

impl Clone for Block

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 Block

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Block

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Block

impl PartialEq for Block

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

Equality operator ==.

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

Inequality operator !=.
