Enum hdk::prelude::ElementEntry
source · [−]pub enum ElementEntry {
Present(Entry),
Hidden,
NotApplicable,
NotStored,
}
Expand description
Represents the different ways the entry_address reference within a Header can be intepreted
Variants
Present(Entry)
The Header has an entry_address reference, and the Entry is accessible.
Hidden
The Header has an entry_address reference, but we are in a public context and the entry is private.
NotApplicable
The Header does not contain an entry_address reference.
NotStored
The Header has an entry but was stored without it. This can happen when you receive gossip of just a header when the header type is a [NewEntryHeader]
Implementations
sourceimpl ElementEntry
impl ElementEntry
sourcepub fn as_option(&self) -> Option<&Entry>
pub fn as_option(&self) -> Option<&Entry>
Provides entry data by reference if it exists
Collapses the enum down to the two possibilities of extant or nonextant Entry data
sourcepub fn into_option(self) -> Option<Entry>
pub fn into_option(self) -> Option<Entry>
Provides entry data as owned value if it exists.
Collapses the enum down to the two possibilities of extant or nonextant Entry data
sourcepub fn to_app_option<A>(&self) -> Result<Option<A>, SerializedBytesError> where
A: TryFrom<SerializedBytes, Error = SerializedBytesError>,
pub fn to_app_option<A>(&self) -> Result<Option<A>, SerializedBytesError> where
A: TryFrom<SerializedBytes, Error = SerializedBytesError>,
Provides deserialized app entry if it exists
same as as_option but handles deserialization anything other than ElementEntry::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
sourcepub 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 than ElementEntry::Present for a Entry::CapGrant returns None
