Struct BlockHeader 

pub struct BlockHeader {
    pub height: u64,
    pub parent: BlockHash,
    pub events_root: Hash,
    pub events_count: u32,
    pub mmr_root: Hash,
    pub timestamp: DateTime<Utc>,
    pub sealer: SealerId,
    pub seal: Sig,
}

Block header containing metadata and proofs.

Fields

height: u64

Block height (monotonically increasing).

parent: BlockHash

Hash of parent block header.

events_root: Hash

Merkle root of events in this block.

events_count: u32

Number of events in this block.

mmr_root: Hash

MMR root after this block (cumulative chain state).

timestamp: DateTime<Utc>

Sealer’s timestamp (must be >= parent timestamp), as Unix millis.

sealer: SealerId

Identity of the sealer who produced this block.

seal: Sig

Sealer’s signature over the header (excluding this field).

Implementations

impl BlockHeader

pub fn signing_bytes(&self) -> Vec<u8>

Get the bytes to be signed (everything except the seal).

pub fn hash(&self) -> BlockHash

Compute the hash of this header.

pub fn with_seal(self, seal: Sig) -> Self

Create a new header with the given seal.

pub fn verify_seal(&self) -> Result<()>

Verify the seal signature.

pub fn validate(&self, parent: Option<&BlockHeader>) -> Result<()>

Validate this header against its parent.

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
