Struct holochain_types::prelude::Element
source · [−]pub struct Element { /* private fields */ }
Expand description
a chain element containing the signed header along with the entry if the header type has one.
Implementations
sourceimpl Element
impl Element
sourcepub 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.
sourcepub 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.
sourcepub fn new(
signed_header: SignedHeaderHashed,
maybe_entry: Option<Entry>
) -> Element
pub fn new(
signed_header: SignedHeaderHashed,
maybe_entry: Option<Entry>
) -> Element
Raw element constructor. Used only when we know that the values are valid.
sourcepub 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
sourcepub fn into_inner(self) -> (SignedHeaderHashed, ElementEntry)
pub fn into_inner(self) -> (SignedHeaderHashed, ElementEntry)
Break this element into its components
sourcepub fn signed_header(&self) -> &SignedHeaderHashed
pub fn signed_header(&self) -> &SignedHeaderHashed
The inner signed-header
sourcepub fn header_address(&self) -> &HoloHash<Header>
pub fn header_address(&self) -> &HoloHash<Header>
Access the header address from this element’s signed header
sourcepub fn header_hashed(&self) -> &HoloHashed<Header>
pub fn header_hashed(&self) -> &HoloHashed<Header>
Access the HeaderHashed from this element’s signed header portion
sourcepub 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.
