Function indyrs::anoncreds::prover_set_credential_attr_tag_policy

pub fn prover_set_credential_attr_tag_policy(
    wallet_handle: WalletHandle, 
    cred_def_id: &str, 
    tag_attrs_json: Option<&str>, 
    retroactive: bool
) -> Box<dyn Future<Item = (), Error = IndyError>>

Set credential attribute tagging policy. Writes a non-secret record marking attributes to tag, and optionally updates tags on existing credentials on the credential definition to match.

The following tags are always present on write: { "schema_id": , "schema_issuer_did": , "schema_name": , "schema_version": , "issuer_did": , "cred_def_id": , "rev_reg_id": , // "None" as string if not present }

The policy sets the following tags for each attribute it marks taggable, written to subsequent credentials and (optionally) all existing credentials on the credential definition: { "attr::::marker": "1", "attr::::value": , }

Arguments

command_handle: command handle to map callback to user context. wallet_handle: wallet handle (created by Wallet::open_wallet). cred_def_id: credential definition id tag_attrs_json: JSON array with names of attributes to tag by policy, or null for all retroactive: boolean, whether to apply policy to existing credentials on credential definition identifier
