Struct Subject 

#[non_exhaustive]
pub struct Subject {
    pub id: String,
    pub session: String,
    pub email: Option<String>,
}

The person a verified credential speaks for.

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: String

The stable subject identifier — the value a table’s privacy declaration names as its subject column matches against.

session: String

The session behind the credential. A deployment that needs instant revocation asks the auth service about this id.

email: Option<String>

Present only when the credential carried a verified address.

Implementations

impl Subject

pub fn new(id: impl Into<String>) -> Self

A subject with only an id, for a verifier that carries no more.

Built rather than written as a literal because the struct is #[non_exhaustive]: an adapter outside this crate cannot name every field, which is what lets a later field be added without breaking every adapter. The builders are the way in.

pub fn session(self, session: impl Into<String>) -> Self

The session behind the credential.

pub fn email(self, email: Option<String>) -> Self

A verified address. A verifier that holds an unverified one passes None: an unverified address is a string the user typed, and a table matching on it would be matching on a claim its own subject controls.
