Struct holochain_types::prelude::DnaDef

pub struct DnaDef {
    pub name: String,
    pub uid: String,
    pub properties: SerializedBytes,
    pub origin_time: Timestamp,
    pub zomes: Vec<(ZomeName, ZomeDef), 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 There is still a lot of code that uses this type, but in function, it has mainly been superseded by DnaManifest.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.

uid: String

A UID for uniquifying this Dna.

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 Header timestamps must come after this time.

zomes: Vec<(ZomeName, ZomeDef), Global>

A vector of zomes associated with your DNA.

Implementations

impl DnaDef

pub fn unique_from_zomes(zomes: Vec<Zome, Global>) -> DnaDef

Create a DnaDef with a random UID, useful for testing

impl DnaDef

pub fn get_zome(&self, zome_name: &ZomeName) -> Result<Zome, ZomeError>

Return a Zome

pub fn get_wasm_zome(
    &self,
    zome_name: &ZomeName
) -> Result<&WasmZome, ZomeError>

Return a Zome, error if not a WasmZome

pub fn modify_phenotype(
    &self,
    uid: String,
    properties: SerializedBytes
) -> DnaDef

Change the “phenotype” of this DNA – the UID and properties – while leaving the “genotype” of actual DNA code intact

Trait Implementations

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

The HashType which this content will be hashed to

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

The HashType which this content will be hashed to

fn hashable_content(&self) -> HashableContentBytes

Return a subset of the content, either as SerializedBytes “content”, which will be used to compute the hash, or as an already precomputed hash which will be used directly

impl PartialEq<DnaDef> for DnaDef

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
