Struct BlockHeader 

pub struct BlockHeader {
    pub parent_hash: Hash,
    pub height: BlockHeight,
    pub timestamp: Timestamp,
    pub tx_root: Hash,
    pub state_root: Hash,
    pub proposer_pubkey: [u8; 32],
    pub proposer_sig: [u8; 64],
}

Block header containing metadata and proposer signature

Fields

parent_hash: Hash

Hash of the parent block (zero for genesis)

height: BlockHeight

Block height (0 for genesis)

timestamp: Timestamp

Block creation timestamp (ms since epoch)

tx_root: Hash

Merkle root of transactions

state_root: Hash

Root hash of state after applying this block

proposer_pubkey: [u8; 32]

Proposer’s Ed25519 public key

proposer_sig: [u8; 64]

Proposer’s signature over the header hash (excluding this field)

Implementations

impl BlockHeader

pub fn new( parent_hash: Hash, height: BlockHeight, timestamp: Timestamp, tx_root: Hash, state_root: Hash, proposer_pubkey: [u8; 32], ) -> Self

Create a new block header (signature must be added separately)

pub fn signing_hash(&self) -> Hash

Compute the hash that the proposer signs This excludes the signature field itself to avoid circular dependency

pub fn hash(&self) -> Hash

Compute the full block header hash (includes signature) This is the hash used to reference the block

pub fn is_genesis(&self) -> bool

Check if this is a genesis block

pub fn set_signature(&mut self, signature: [u8; 64])

Set the proposer signature

Trait Implementations

impl Clone for BlockHeader

fn clone(&self) -> BlockHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlockHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BlockHeader

fn eq(&self, other: &BlockHeader) -> 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 BlockHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for BlockHeader
