Errors that can occur during Claim 169 QR decoding.

This enum covers all errors in the decoding pipeline, from Base45 decoding through CBOR parsing to signature verification and timestamp validation.

Converting from CryptoError

CryptoError automatically converts to Claim169Error via the From trait:

let crypto_err = CryptoError::VerificationFailed;
let claim_err: Claim169Error = crypto_err.into();

Variants

Base45Decode(String)

Invalid Base45 encoding in QR string

Decompress(String)

Failed to decompress zlib data

DecompressLimitExceeded

Decompressed data exceeds safety limit

Trait Implementations

impl Debug for Claim169Error

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

Formats the value using the given formatter.

impl Display for Claim169Error

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

Formats the value using the given formatter.

impl Error for Claim169Error

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
