Struct holochain_types::prelude::Element
[−]pub struct Element {
pub signed_header: SignedHashed<Header>,
pub entry: ElementEntry,
}
Expand description
a chain element containing the signed header along with the entry if the header type has one.
Fields
signed_header: SignedHashed<Header>
The signed header for this element
entry: ElementEntry
If there is an entry associated with this header it will be here. If not, there will be an enum variant explaining the reason.
Implementations
impl Element
impl Element
pub fn as_header_mut(&mut self) -> &mut Header
pub fn as_header_mut(&mut self) -> &mut Header
Mutable reference to the Header content. This is useless and dangerous in production usage. Guaranteed to make hashes and signatures mismatch whatever the Header is mutated to (at least). This may be useful for tests that rely heavily on mocked and fixturated data.
pub fn as_entry_mut(&mut self) -> &mut ElementEntry
pub fn as_entry_mut(&mut self) -> &mut ElementEntry
Mutable reference to the ElementEntry. This is useless and dangerous in production usage. Guaranteed to make hashes and signatures mismatch whatever the ElementEntry is mutated to (at least). This may be useful for tests that rely heavily on mocked and fixturated data.
pub fn new(
signed_header: SignedHashed<Header>,
maybe_entry: Option<Entry>
) -> Element
pub fn new(
signed_header: SignedHashed<Header>,
maybe_entry: Option<Entry>
) -> Element
Raw element constructor. Used only when we know that the values are valid.
pub fn privatized(self) -> Element
pub fn privatized(self) -> Element
If the Element contains private entry data, set the ElementEntry to Hidden so that it cannot be leaked
pub fn into_inner(self) -> (SignedHashed<Header>, ElementEntry)
pub fn into_inner(self) -> (SignedHashed<Header>, ElementEntry)
Break this element into its components
pub fn signed_header(&self) -> &SignedHashed<Header>
pub fn signed_header(&self) -> &SignedHashed<Header>
The inner signed-header
pub fn header_address(&self) -> &HoloHash<Header>
pub fn header_address(&self) -> &HoloHash<Header>
Access the header address from this element’s signed header
pub fn header_hashed(&self) -> &HoloHashed<Header>
pub fn header_hashed(&self) -> &HoloHashed<Header>
Access the HeaderHashed from this element’s signed header portion
pub fn entry(&self) -> &ElementEntry
pub fn entry(&self) -> &ElementEntry
Access the Entry portion of this element as an ElementEntry, which includes the context around the presence or absence of the entry.
