Enum ReceiptError

pub enum ReceiptError {
    Jcs(JcsError),

Receipt errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Jcs(JcsError)

Canonicalization failed (unsafe numbers in body).

Serde(Error)

Serialization failed.

Key(KeyError)

Key/signature failure.

Base64

Signature or public key not valid base64.

KeyMismatch(String)

The receipt’s embedded public key does not match the keyring entry for its key id (substitution attempt).

DuplicateKey(String)

Round-15 F4: a JSON object at some nesting level carried a duplicate key. Rejecting these closes the last-wins vs first-wins auditor split-brain that would otherwise let a hostile issuer sign under one interpretation while an external audit tool displayed the other.

SemanticInvariant(String)

Round-16 F8: a receipt carries a semantically-invalid field (currently: AtifTrajectory.retroactive == false). Distinct from Serde and DuplicateKey so ops triage can name the class.

Trait Implementations

impl Debug for ReceiptError

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

Formats the value using the given formatter.

impl Display for ReceiptError

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

Formats the value using the given formatter.

impl Error for ReceiptError

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.

impl From<Error> for ReceiptError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<JcsError> for ReceiptError

fn from(source: JcsError) -> Self

Converts to this type from the input type.

impl From<KeyError> for ReceiptError

fn from(source: KeyError) -> Self

Converts to this type from the input type.
