Struct holochain_types::prelude::dna_def::DnaDef

pub struct DnaDef {
    pub name: String,
    pub network_seed: String,
    pub properties: SerializedBytes,
    pub origin_time: Timestamp,
    pub integrity_zomes: Vec<(ZomeName, IntegrityZomeDef), Global>,
    pub coordinator_zomes: Vec<(ZomeName, CoordinatorZomeDef), Global>,
}

The definition of a DNA: the hash of this data is what produces the DnaHash.

Historical note: This struct was written before DnaManifest appeared. It is included as part of a DnaFile. There is still a lot of code that uses this type, but in function, it has mainly been superseded by DnaManifest. Hence, this type can basically be thought of as a fully validated, normalized DnaManifest

Fields

name: String

The friendly “name” of a Holochain DNA.

network_seed: String

The network seed of a DNA is included in the computation of the DNA hash. The DNA hash in turn determines the network peers and the DHT, meaning that only peers with the same DNA hash of a shared DNA participate in the same network and co-create the DHT. To create a separate DHT for the DNA, a unique network seed can be specified.

properties: SerializedBytes

Any arbitrary application properties can be included in this object.

origin_time: Timestamp

The time used to denote the origin of the network, used to calculate time windows during gossip. All Action timestamps must come after this time.

integrity_zomes: Vec<(ZomeName, IntegrityZomeDef), Global>

A vector of zomes associated with your DNA.

coordinator_zomes: Vec<(ZomeName, CoordinatorZomeDef), Global>

A vector of zomes that do not affect the DnaHash.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for DnaDef

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<DnaDef, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<DnaDef, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for DnaDef

fn clone(&self) -> DnaDef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DnaDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DnaDef

fn deserialize<__D>(
    __deserializer: __D
) -> Result<DnaDef, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl HashableContent for DnaDef

type HashType = Dna

fn hash_type(&self) -> <DnaDef as HashableContent>::HashType

The HashType which this content will be hashed to

fn hashable_content(&self) -> HashableContentBytes

impl PartialEq<DnaDef> for DnaDef

fn eq(&self, other: &DnaDef) -> bool
