Function hdk_crud::get_latest_for_entry [−][src]

entry_hash: EntryHash,
get_options: GetOptions
) -> ExternResult<OptionEntryAndHash<T>>
Expand description
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 HeaderHash, as opposed to the HeaderHash of the Header 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
