Enum TranscriptError 

pub enum TranscriptError {
    Missing(&'static str),
    Encoding(String),
    VersionMismatch {
        claim: String,
        expected: String,
    },
}

Errors arising during TranscriptT1 operations.

Variants

Missing(&'static str)

A required field is missing (e.g. subject.id both bytes and utf8 are None).

Encoding(String)

CBOR encoding failed during transcript absorption.

VersionMismatch

Transcript version mismatch — Claim’s transcript_version does not match the verifier’s expected version. Rejects downgrade attacks (§6 Q5).

Fields

claim: String

The version tag found on the Claim.

expected: String

The version tag required by the verifier.

Trait Implementations

impl Debug for TranscriptError

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

Formats the value using the given formatter.

impl Display for TranscriptError

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

Formats the value using the given formatter.

impl Error for TranscriptError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
