Header for an L2 block.

Fields

version: u32

Block version; must match network consensus version.

network_id: [u8; 32]

Network ID (32 bytes), serialized as 0x hex.

epoch: u64

Epoch number.

prev_block_root: [u8; 32]

Previous block root (32 bytes), serialized as 0x hex.

body_root: [u8; 32]

Body root (32 bytes), serialized as 0x hex.

data_count: u32

Count of data items (bytes) in the body.

emissions_count: u32

Count of emissions in the body.

proposer_pubkey: [u8; 48]

Proposer public key (48 bytes), serialized as 0x hex.

Implementations

impl L2BlockHeader

pub fn calculate_root(&self) -> Hash32

Calculates the HEADER_ROOT using the spec function.

pub fn validate_version(&self, expected_version: u32) -> Result<(), HeaderError>

Validates that the header version matches the expected consensus version.

pub fn validate_counts( &self, data_len: usize, emissions_len: usize, ) -> Result<(), HeaderError>

Validates that data_count and emissions_count match the provided body lengths.

Trait Implementations

impl Clone for L2BlockHeader

fn clone(&self) -> L2BlockHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for L2BlockHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for L2BlockHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for L2BlockHeader

fn eq(&self, other: &L2BlockHeader) -> 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.

impl Serialize for L2BlockHeader

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
