Enum PresentationAuthError 

pub enum PresentationAuthError {
    Wire(WireError),
    NonceLength,
    Challenge(ChallengeError),
    Resolve(CredentialError),
    Denied(Denied),
    PolicyDenied {
        reason: String,
    },
    Policy(OrgError),
}

Errors from authenticate_presentation (thiserror, exhaustive).

Variants

Wire(WireError)

The Auths-Presentation wire shape was malformed.

NonceLength

The presented nonce was not exactly 32 bytes.

Challenge(ChallengeError)

No live single-use challenge matched (absent, replayed, or expired).

Resolve(CredentialError)

The issuer/subject KELs or the credential could not be resolved.

Denied(Denied)

The presentation verified-as-a-process but was not honored (see the inner reason).

PolicyDenied

The presentation verified and the holder is authenticated, but the issuer’s org policy denied the principal (403, not 401 — authentication succeeded).

Fields

reason: String

The typed denial reason from the policy engine.

Policy(OrgError)

The issuer’s org policy could not be loaded or evaluated — fail closed (treated as a denial; the principal is not authorized when policy cannot be confirmed).

Implementations

impl PresentationAuthError

pub fn http_status(&self) -> u16
