Expand description

A credential holder that stores AnonCreds credentials and matches them to proof requests.

Implementations§

Source§

impl CredentialHolder

Source

pub fn new() -> Self

Create a new, empty credential holder.

Source

pub fn store_credential(&mut self, credential: AnonCredsCredential) -> String

Store a credential and return its local identifier.

Source

pub fn find_credentials_for_request( &self, request: &ProofRequest, ) -> Vec<(&str, &AnonCredsCredential)>

Find all stored credentials that satisfy a proof request.

Returns a list of (credential_id, credential) pairs.

Source

pub fn create_proof_response( &self, credential_id: &str, request: &ProofRequest, ) -> Option<ProofResponse>

Build a proof response from a stored credential for a proof request.

Reveals all requested attributes from the given credential. Returns None if the credential does not match the request or is not found.

Source

pub fn len(&self) -> usize

Return the number of stored credentials.

Source

pub fn is_empty(&self) -> bool

Check whether the holder has no credentials.

Source

pub fn get(&self, id: &str) -> Option<&AnonCredsCredential>

Get a credential by its local identifier.
