Enum IssuerScope 

pub enum IssuerScope {
    Pairwise,
    Directed,
    Public,
}

The correlation scope an issuer declares for its own identifier, carried as the REQUIRED top-level issuerScope of every DTG credential (DTG Core Credentials §Correlation Scope).

Ordered, narrowest first

pairwise < directed < public, and the derived Ord follows it. Where a profile or a credential type states a minimum, a declaration narrower than that minimum does not satisfy it: see IssuerScope::satisfies.

A declaration about the issuer only

A credential declares the scope of the identifier in issuer and of nothing else — not its subject’s, not its counterparty’s. A verifier that needs the counterparty’s scope reads it from a credential the counterparty issued.

Serialized exactly as pairwise, directed or public, and parsed case-sensitively: "Public" is not a declaration, and a credential carrying it is refused.

Variants

Pairwise

Known to exactly one counterparty; correlation confined to this one relationship.

Directed

Known to a set of counterparties the holder chooses, and no further.

Public

Unbounded; ordinarily published so that it can be found.

Implementations

impl IssuerScope

pub fn as_str(&self) -> &'static str

pub fn satisfies(&self, minimum: IssuerScope) -> bool
