Enum ChallengeOutcome 

pub enum ChallengeOutcome {
    NotRequested,
    PresentButUnchecked,
    NoResponse,
    NoEstablishedKey,
    Verified {
        signed_at: String,
    },
    Failed {
        reason: String,
    },
}

The outcome of the challenge-response handshake within a presentation.

Variants

NotRequested

The verifier passed no nonce, so no liveness was checked.

PresentButUnchecked

A response is present but the verifier passed no nonce to check it.

NoResponse

A nonce was requested but the presentation carries no response.

NoEstablishedKey

A response is present but the card did not verify key-bound, so there is no established key to check the response against.

Verified

The bearer proved live control of the card key; carries the response’s bearer-signed signed_at.

Fields

signed_at: String

Failed

The response was checked against the established key and failed.

Fields

reason: String

Implementations

impl ChallengeOutcome

pub fn is_ok(&self) -> bool

Vacuously true unless a nonce was requested and the check did not succeed — i.e. a signature from an unverified key never counts as a live-control success.

Trait Implementations

impl Debug for ChallengeOutcome

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
