Enum holochain_types::prelude::RecordEntry
pub enum RecordEntry<E = Entry>{
Present(E),
Hidden,
NA,
NotStored,
}
Expand description
Represents the different ways the entry_address reference within an action can be interpreted
Variants§
Present(E)
The Action has an entry_address reference, and the Entry is accessible.
Hidden
The Action has an entry_address reference, but we are in a public context and the entry is private.
NA
The Action does not contain an entry_address reference, so there will never be an associated Entry.
NotStored
The Action has an entry but was stored without it.
This can happen when you receive gossip of just an action
when the action type is a crate::EntryCreationAction
,
in particular for certain DhtOps
Implementations§

impl<E> RecordEntry<E>
pub fn new(
vis: Option<&EntryVisibility>,
maybe_entry: Option<E>
) -> RecordEntry<E>
pub fn new( vis: Option<&EntryVisibility>, maybe_entry: Option<E> ) -> RecordEntry<E>
Constructor based on Action data
pub fn as_option(&self) -> Option<&E>
pub fn as_option(&self) -> Option<&E>
Provides entry data by reference if it exists
Collapses the enum down to the two possibilities of extant or nonextant Entry data
pub fn into_option(self) -> Option<E>
pub fn into_option(self) -> Option<E>
Provides entry data as owned value if it exists.
Collapses the enum down to the two possibilities of extant or nonextant Entry data
pub fn to_app_option<A>(&self) -> Result<Option<A>, SerializedBytesError>
pub fn to_app_option<A>(&self) -> Result<Option<A>, SerializedBytesError>
Provides deserialized app entry if it exists
same as as_option but handles deserialization anything other than RecordEntry::Present returns None a present entry that fails to deserialize cleanly is an error a present entry that deserializes cleanly is returned as the provided type A
pub fn as_ref<'a>(&'a self) -> RecordEntry<&'a E>
pub fn as_ref<'a>(&'a self) -> RecordEntry<&'a E>
Use a reference to the Entry, if present
pub fn to_grant_option(&self) -> Option<ZomeCallCapGrant>
pub fn to_grant_option(&self) -> Option<ZomeCallCapGrant>
Provides CapGrantEntry if it exists
same as as_option but handles cap grants anything other tha RecordEntry::Present for a Entry::CapGrant returns None
If no entry is available, return Hidden, else return Present
pub fn or_not_applicable(entry: Option<E>) -> RecordEntry<E>
pub fn or_not_applicable(entry: Option<E>) -> RecordEntry<E>
If no entry is available, return NotApplicable, else return Present
pub fn or_not_stored(entry: Option<E>) -> RecordEntry<E>
pub fn or_not_stored(entry: Option<E>) -> RecordEntry<E>
If no entry is available, return NotStored, else return Present
