Struct hdk_crud::retrieval::get_latest_for_entry::GetLatestEntry

pub struct GetLatestEntry {}

Implementations

impl GetLatestEntry

pub fn get_latest_for_entry<T: 'static + TryFrom<SerializedBytes, Error = SerializedBytesError>>( &self, entry_hash: EntryHash, get_options: GetOptions ) -> ExternResult<Option<WireRecord<T>>>

If an entry at the entry_hash has multiple updates to itself, this function will sort through them by timestamp in order to return the contents of the latest update. It also has the special behaviour of returning the ORIGINAL ActionHash, as opposed to the ActionHash of the Action that performed that latest update. This is useful if you want hashes in your application to act consistently, almost acting as an “id” in a centralized system. It simplifies traversal of the update tree, since all updates made by the client can reference the original, instead of updates reference updates

Trait Implementations

impl Clone for GetLatestEntry

fn clone(&self) -> GetLatestEntry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GetLatestEntry

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

Formats the value using the given formatter.

impl PartialEq<GetLatestEntry> for GetLatestEntry

fn eq(&self, other: &GetLatestEntry) -> 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.
