Struct Subject 

#[non_exhaustive]
pub struct Subject {
    pub id: Option<Uri>,
    pub properties: IndexMap<String, Value>,
}

Available on crate feature vc only.

A credentialSubject: the optional id of the subject and the claims about it.

A subject without id makes a bearer credential.

Examples

use identity_kit::did::Uri;
use identity_kit::vc::Subject;
use serde_json::json;

let subject = Subject::new(Uri::parse("did:example:ebfeb1f712ebc6f1c276e12ec21")?)
    .with_property("alumniOf", json!({ "name": "Example University" }));
assert_eq!(
    serde_json::to_string(&subject)?,
    r#"{"id":"did:example:ebfeb1f712ebc6f1c276e12ec21","alumniOf":{"name":"Example University"}}"#
);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: Option<Uri>

The identifier of the subject, absent in a bearer credential.

properties: IndexMap<String, Value>

The claims about the subject, in insertion order.

Implementations
