Enum HeaderFamily 

pub enum HeaderFamily {
    Stock,
    Blake2bV2,
}

The two header families of SPEC 3.2, named after the header they carry.

Variants

Stock

Stock 80-byte header, SHA-256d: beside btc or tbtc4 (family: 'stock' in siding/lib/parents.mjs).

Blake2bV2

Knots 164-byte v2 header, BLAKE2b: beside xbt or txbt4 (family: 'blake2b').

Implementations

impl HeaderFamily

pub const fn wire_size(self) -> usize

The family’s header size in bytes: 80 or 164.

pub const fn pow_hash_name(self) -> &'static str

The kernel’s name for the family’s proof-of-work hash: sha256d or knots:blake2b-v2.

pub const fn from_version(version: u32) -> HeaderFamily

The family a version word claims: bit 31 set means v2. This is the kernel’s structVariants selector, useful when the bytes’ provenance is unknown; a validator knows its family from the chain document’s parent and should use HeaderFamily::decode with that.

pub fn decode(self, bytes: &[u8]) -> Result<Header, Error>

Decodes bytes as this family’s header.
