Struct holochain_core_types::signature::Provenance

pub struct Provenance(pub Address, pub Signature);

Provenance is a tuple of initiating agent public key and signature of some item being signed this type is used in headers and in capability requests where the item being signed is implicitly known by context

Methods

impl Provenance

pub fn new(source: Address, signature: Signature) -> Self

Creates a new provenance instance with source typically being an agent address (public key) and the signature some signed data using the private key associated with the public key.

pub fn source(&self) -> Address

pub fn signature(&self) -> Signature
