Struct holochain_types::prelude::header::Dna
[−]Expand description
The Dna Header is always the first header in a source chain
Fields
timestamp: Timestamp
hash: HoloHash<Dna>
Implementations
impl Dna
impl Dna
pub fn from_builder(hash: HoloHash<Dna>, builder: HeaderBuilderCommon) -> Dna
pub fn from_builder(hash: HoloHash<Dna>, builder: HeaderBuilderCommon) -> Dna
The Dna header can’t implement HeaderBuilder because it lacks a
prev_header
field, so this helper is provided as a special case
