Struct holochain_zome_types::dna_def::DnaDef

pub struct DnaDef {
    pub name: String,
    pub modifiers: DnaModifiers,
    pub integrity_zomes: IntegrityZomes,
    pub coordinator_zomes: CoordinatorZomes,
}

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 There is still a lot of code that uses this type, but in function, it has mainly been superseded by DnaManifest.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

modifiers: DnaModifiers

Modifiers of this DNA - the network seed, properties and origin time - as opposed to the actual DNA code. The modifiers are included in the DNA hash computation.

integrity_zomes: IntegrityZomes

A vector of zomes associated with your DNA.

coordinator_zomes: CoordinatorZomes

A vector of zomes that do not affect the DnaHash.

Implementations

impl DnaDef

pub fn unique_from_zomes( integrity: Vec<IntegrityZome>, coordinator: Vec<CoordinatorZome> ) -> DnaDef

impl DnaDef

pub fn all_zomes(&self) -> impl Iterator<Item = (&ZomeName, &ZomeDef)>

Get all zomes including the integrity and coordinator zomes.

impl DnaDef

pub fn get_integrity_zome( &self, zome_name: &ZomeName ) -> Result<IntegrityZome, ZomeError>

Find an integrity zome from a ZomeName.

pub fn is_integrity_zome(&self, zome_name: &ZomeName) -> bool

Check if a zome is an integrity zome.

pub fn get_coordinator_zome( &self, zome_name: &ZomeName ) -> Result<CoordinatorZome, ZomeError>

Find a coordinator zome from a ZomeName.

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

Find a any zome from a ZomeName.

pub fn get_all_coordinators(&self) -> Vec<CoordinatorZome>

Get all the CoordinatorZomes for this dna

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

Return a Zome, error if not a WasmZome

pub fn get_wasm_zome_hash( &self, zome_name: &ZomeName ) -> Result<WasmHash, ZomeError>

Return the Wasm Hash for Zome, error if not a Wasm type Zome

pub fn set_name(&self, name: String) -> Self

Set the DNA’s name.

pub fn update_modifiers(&self, dna_modifiers: DnaModifiersOpt) -> Self

Change the DNA modifiers – the network seed, properties and origin time – while leaving the actual DNA code intact.

pub fn topology(&self, cutoff: Duration) -> Topology

Get the topology to use for kitsune gossip

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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::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) -> Self::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 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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DnaDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&DnaDef> for SerializedBytes

type Error = SerializedBytesError

The type returned in the event of a conversion error.

fn try_from(t: &DnaDef) -> Result<SerializedBytes, SerializedBytesError>

Performs the conversion.

impl TryFrom<DnaDef> for SerializedBytes

type Error = SerializedBytesError

The type returned in the event of a conversion error.

fn try_from(t: DnaDef) -> Result<SerializedBytes, SerializedBytesError>

Performs the conversion.

impl TryFrom<SerializedBytes> for DnaDef

type Error = SerializedBytesError

The type returned in the event of a conversion error.

fn try_from(sb: SerializedBytes) -> Result<DnaDef, SerializedBytesError>

Performs the conversion.
