    pub properties: SerializedBytes,

Expand description

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 There is still a lot of code that uses this type, but in function, it has mainly been superseded by DnaManifest.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].
