Enum Header 

pub enum Header {
    Stock(StockHeader),
    Blake2bV2(Blake2bV2Header),
}

A header of either family, with the operations a sidestr validator needs dispatched to the right one.

Variants

Stock(StockHeader)

An 80-byte stock header.

Blake2bV2(Blake2bV2Header)

A 164-byte Knots v2 header.

Implementations

impl Header

pub const fn family(&self) -> HeaderFamily

Which family this header belongs to.

pub const fn version(&self) -> u32

The raw wire version.

pub const fn prev_block_hash(&self) -> BlockHash

The previous block’s hash.

pub const fn merkle_root(&self) -> [u8; 32]

The merkle root, wire order.

pub fn time(&self) -> u32

The consensus block time (for v2, with the offset applied when flagged).

pub const fn bits(&self) -> u32

Compact target.

pub const fn nonce(&self) -> u32

The (first) nonce.

pub const fn height(&self) -> Option<u32>

The committed height: a v2 header carries it, a stock header does not (siding’s blockHeight then reads the coinbase’s BIP 34 push, which is sidestr-core’s job).

pub fn hash(&self) -> BlockHash

The block hash — the family’s proof-of-work hash, display order.

pub fn encode(&self) -> EncodedHeader

The wire bytes.

pub fn target(&self) -> Result<Target, Error>

The target bits encodes.

pub fn meets_target(&self) -> bool

hash ≤ target(bits).

pub fn check_pow(&self, pow_limit: &Target) -> Result<(), Error>

SPEC 4 step 1 against the chain document’s powLimit; see check_pow.

pub fn signet_preimage(&self, stripped_merkle_root: [u8; 32]) -> [u8; 72]

The 72-byte BIP-325 preimage with the stripped merkle root in place.

pub fn block_data(&self, stripped_merkle_root: [u8; 32]) -> [u8; 32]

The BIP-325 block data the block signature commits to (SPEC 4 step 2).
