Enum holochain_types::prelude::element::ElementEntry [−][src]
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.
Tuple Fields of Present
0: Entry
The Header has an entry_address reference, but we are in a public context and the entry is private.
The Header does not contain an entry_address reference.
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
Provides entry data by reference if it exists
Collapses the enum down to the two possibilities of extant or nonextant Entry data
Provides entry data as owned value if it exists.

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
Provides CapGrantEntry if it exists
same as as_option but handles cap grants anything other than ElementEntry::Present for a Entry::CapGrant returns None
