Struct holochain_types::prelude::action::Dna
[−]Expand description
The Dna Action is always the first action in a source chain
Fields
timestamp: Timestamp
hash: HoloHash<Dna>
Implementations
impl Dna
impl Dna
The Dna action can’t implement ActionBuilder because it lacks a
prev_action
field, so this helper is provided as a special case
pub fn from_builder(hash: HoloHash<Dna>, builder: ActionBuilderCommon) -> Dna
Trait Implementations
impl ActionUnweighed for Dna
impl ActionUnweighed for Dna
type Weighed = Dna
type Weight = ()
fn weighed(self, _weight: ()) -> Dna
fn weighed(self, _weight: ()) -> Dna
Add a weight to this unweighed action, making it “weighed”.
The weight is determined by the
weigh
callback, which is run on the
unweighed version of this action. Read morefn weightless(self) -> Self::Weighed
fn weightless(self) -> Self::Weighed
Add zero weight to this unweighed action, making it “weighed”.
impl ActionWeighed for Dna
impl ActionWeighed for Dna
type Unweighed = Dna
type Weight = ()
fn into_action(self) -> Action
fn into_action(self) -> Action
Construct the full Action enum with this variant.
fn unweighed(self) -> <Dna as ActionWeighed>::Unweighed
fn unweighed(self) -> <Dna as ActionWeighed>::Unweighed
Erase the rate limiting weight info, creating an “unweighed” version
of this action. This is used primarily by validators who need to run the
weigh
callback on an action they received, and want to make sure their
callback is not using the predefined weight to influence the result. Read moreimpl<'arbitrary> Arbitrary<'arbitrary> for Dna

impl HashableContent for Dna
impl HashableContent for Dna
fn hash_type(&self) -> <Dna as HashableContent>::HashType
fn hash_type(&self) -> <Dna as HashableContent>::HashType
The HashType which this content will be hashed to
fn hashable_content(&self) -> HashableContentBytes
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 Read more
