Struct holochain_types::prelude::element::Element [−][src]
pub struct Element { /* fields omitted */ }
Expand description
a chain element containing the signed header along with the entry if the header type has one.
Implementations
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.
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.
Raw element constructor. Used only when we know that the values are valid.
Break this element into its components
The inner signed-header
Access the header address from this element’s signed header
Access the HeaderHashed from this element’s signed header portion
Access the Entry portion of this element as an ElementEntry, which includes the context around the presence or absence of the entry.
