Enum CredentialProof 

pub enum CredentialProof<C, AttributeType>
where
    C: Curve,
    AttributeType: Attribute<<C as Curve>::Scalar>,
{
    Account {
        created: DateTime<Utc>,
        network: Network,
        cred_id: CredentialRegistrationID,
        issuer: IpIdentity,
        proofs: Vec<(AtomicStatement<C, AttributeTag, AttributeType>, AtomicProof<C, AttributeType>)>,
    },
    Web3Id {
        created: DateTime<Utc>,
        holder: Ed25519PublicKey<CredentialHolderIdRole>,
        network: Network,
        contract: ContractAddress,
        ty: BTreeSet<String>,
        commitments: SignedCommitments<C>,
        proofs: Vec<(AtomicStatement<C, String, AttributeType>, AtomicProof<C, AttributeType>)>,
    },
}

A proof corresponding to one CredentialStatement. This contains almost all the information needed to verify it, except the issuer’s public key in case of the Web3Id proof, and the public commitments in case of the Account proof.

Variants

Account

Fields

created: DateTime<Utc>

Creation timestamp of the proof.

network: Network

cred_id: CredentialRegistrationID

Reference to the credential to which this statement applies.

issuer: IpIdentity

Issuer of this credential, the identity provider index on the relevant network.

proofs: Vec<(AtomicStatement<C, AttributeTag, AttributeType>, AtomicProof<C, AttributeType>)>

Web3Id

Fields

created: DateTime<Utc>

Creation timestamp of the proof.

holder: Ed25519PublicKey<CredentialHolderIdRole>

Owner of the credential, a public key.

network: Network

contract: ContractAddress

Reference to a specific smart contract instance.

ty: BTreeSet<String>

The credential type. This is chosen by the provider to provide some information about what the credential is about.

commitments: SignedCommitments<C>

Commitments that the user has. These are all the commitments that are part of the credential, indexed by the attribute tag.

proofs: Vec<(AtomicStatement<C, String, AttributeType>, AtomicProof<C, AttributeType>)>

Individual proofs for statements.
