Enum hdk::prelude::dependencies::holochain_integrity_types::Action

pub enum Action {

Action contains variants for each type of action.

This struct really defines a local source chain, in the sense that it implements the pointers between hashes that a hash chain relies on, which are then used to check the integrity of data using cryptographic hash functions.

Variants

Dna(Dna)

AgentValidationPkg(AgentValidationPkg)

InitZomesComplete(InitZomesComplete)

CreateLink(CreateLink<RateWeight>)

DeleteLink(DeleteLink)

OpenChain(OpenChain)

CloseChain(CloseChain)

Create(Create<EntryRateWeight>)

Update(Update<EntryRateWeight>)

Delete(Delete<RateWeight>)

Returns a copy of the value.

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

    __deserializer: __D
) -> Result<Action, <__D as Deserializer<'de>>::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Action> for ActionType

fn from(action: &Action) -> ActionType

Converts to this type from the input type.

impl From<EntryCreationAction> for Action

fn from(e: EntryCreationAction) -> Action

Converts to this type from the input type.

impl From<HoloHashed<Action>> for Action

fn from(action_hashed: HoloHashed<Action>) -> Action

Converts to this type from the input type.

impl<I> From<I> for Actionwhere
    I: ActionWeighed,

fn from(i: I) -> Action

impl Hash for Action

fn hash<__H>(&self, state: &mut __H)where
    __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where

The HashType which this content will be hashed to

fn hashable_content(&self) -> HashableContentBytes

impl PartialEq<Action> for Action

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

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

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