Struct DTGCommon 

pub struct DTGCommon {
    pub context: Vec<String>,
    pub type_: Vec<String>,
    pub issuer: String,
    pub valid_from: DateTime<Utc>,
    pub valid_until: Option<DateTime<Utc>>,
    pub credential_subject: CredentialSubject,
    pub proof: Option<DataIntegrityProof>,
}

All DTG Credentials follow a common structure.

Fields

context: Vec<String>

JSON-LD links to contexts Must contain at least: https://www.w3.org/ns/credentials/v2 https://firstperson.network/credentials/dtg/v1

type_: Vec<String>

Credential type identifiers Must contain at least: DTGCredential VerifiableCredential

issuer: String

DID of the entity issuing this credential

valid_from: DateTime<Utc>

ISO 8601 format of when this credentials become valid from

valid_until: Option<DateTime<Utc>>

ISO 8601 format of when these credentials are valid to

credential_subject: CredentialSubject

The assertion between the entities involved

proof: Option<DataIntegrityProof>

Cryptographic proof of credential authenticity

Implementations

impl DTGCommon

pub fn signed(&self) -> bool

Has this credential been signed? Returns true if a proof exists NOTE: This does NOT validate the proof itself

pub fn issuer(&self) -> &str

Returns the issuer DID

pub fn subject(&self) -> &str

Returns the subject DID

pub fn valid_from(&self) -> DateTime<Utc>

The credential is valid from this timestamp

pub fn valid_until(&self) -> Option<DateTime<Utc>>

The credential is valid until this timestamp, if set
