Expand description

a chain element containing the signed header along with the entry if the header type has one.

Implementations

[src]

impl Element

[src]

pub fn new(
signed_header: SignedHeaderHashed,

[src]

pub fn signature(&self) -> &Signature

Access the signature from this element’s signed header

[src]

pub fn header_address(&self) -> &HoloHash<Header>

Access the header address from this element’s signed header

Access the Header from this element’s signed header

[src]

pub fn header_hashed(&self) -> &HoloHashed<Header>

Access the HeaderHashed from this element’s signed header portion

[src]

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.
