Struct holochain::prelude::prelude::dependencies::holochain_integrity_types::DeleteLink

pub struct DeleteLink {
    pub author: HoloHash<Agent>,
    pub timestamp: Timestamp,
    pub action_seq: u32,
    pub prev_action: HoloHash<Action>,
    pub base_address: HoloHash<AnyLinkable>,
    pub link_add_address: HoloHash<Action>,
}

Declares that a previously made Link should be nullified and considered removed.

Fields

author: HoloHash<Agent>

timestamp: Timestamp

action_seq: u32

prev_action: HoloHash<Action>

base_address: HoloHash<AnyLinkable>

this is redundant with the CreateLink action but needs to be included to facilitate DHT ops this is NOT exposed to wasm developers and is validated by the subconscious to ensure that it always matches the base_address of the CreateLink

link_add_address: HoloHash<Action>

The address of the CreateLink being reversed

Implementations

impl DeleteLink

pub fn from_builder( common: ActionBuilderCommon, link_add_address: HoloHash<Action>, base_address: HoloHash<AnyLinkable> ) -> DeleteLink

Trait Implementations

impl ActionBuilder<DeleteLink> for DeleteLink

fn build(self, common: ActionBuilderCommon) -> DeleteLink

impl ActionUnweighed for DeleteLink

type Weighed = DeleteLink

type Weight = ()

fn weighed(self, _weight: ()) -> DeleteLink

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.

fn weightless(self) -> Self::Weighed

Add zero weight to this unweighed action, making it “weighed”.

impl ActionWeighed for DeleteLink

type Unweighed = DeleteLink

type Weight = ()

fn into_action(self) -> Action

Construct the full Action enum with this variant.

fn unweighed(self) -> <DeleteLink 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.

impl<'arbitrary> Arbitrary<'arbitrary> for DeleteLink

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<DeleteLink, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<DeleteLink, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for DeleteLink

fn clone(&self) -> DeleteLink

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeleteLink

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeleteLink

fn deserialize<__D>( __deserializer: __D ) -> Result<DeleteLink, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<(DeleteLink, ActionBuilderCommon)> for DeleteLink

fn from(_: (DeleteLink, ActionBuilderCommon)) -> DeleteLink

Converts to this type from the input type.

impl Hash for DeleteLink

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 H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl HashableContent for DeleteLink

type HashType = Action

The HashType which this content will be hashed to

fn hash_type(&self) -> <DeleteLink 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<DeleteLink> for DeleteLink

fn eq(&self, other: &DeleteLink) -> 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 DeleteLink

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

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<&'a Action> for &'a DeleteLink

type Error = WrongActionError
