[][src]Function indyrs::anoncreds::prover_search_credentials

pub fn prover_search_credentials(
    wallet_handle: IndyHandle,
    query_json: Option<&str>
) -> Box<dyn Future<Item = (IndyHandle, usize), Error = IndyError>>

Search for credentials stored in wallet. Credentials can be filtered by tags created during saving of credential.

Instead of immediately returning of fetched credentials this call returns search_handle that can be used later to fetch records by small batches (with fetch_credentials).

Arguments

  • wallet_handle: wallet handler (created by Wallet::open_wallet).
  • query_json: Wql query filter for credentials searching based on tags. where query: indy-sdk/doc/design/011-wallet-query-language/README.md

Returns

  • search_handle: Search handle that can be used later to fetch records by small batches (with fetch_credentials)
  • total_count: Total count of records
