Get the issuer metadata (for the discovery endpoint).

pub async fn generate_nonce(&self, lifetime_secs: u64) -> String

Generate a fresh c_nonce.

pub async fn validate_nonce(&self, nonce: &str) -> bool

Validate a c_nonce.

pub async fn consume_nonce(&self, nonce: &str) -> bool

Consume a c_nonce (single use).

pub async fn create_offer( &self, credential_config_ids: Vec<String>, subject_id: &str, ) -> Result<CredentialOffer>

Create a credential offer with a pre-authorized code.

pub async fn validate_pre_auth_code( &self, code: &str, ) -> Result<(String, String)>

Validate a pre-authorized code and return (config_id, subject_id).

pub async fn issue_credential( &self, request: &CredentialRequest, subject_id: &str, credential_data: Option<Value>, ) -> Result<CredentialResponse>
