}

Error type for all in-toto related errors.

Variants

BadSignature

The metadata had a bad signature.

Encoding(String)

There was a problem encoding or decoding.

IllegalArgument(String)

An illegal argument was passed into a function.

NoSupportedHashAlgorithm

There were no available hash algorithms.

NotFound

The metadata or target was not found.

Opaque(String)

Opaque error type, to be interpreted similar to HTTP 500. Something went wrong, and you may or may not be able to do anything about it.

Programming(String)

There was a library internal error. These errors are ALWAYS bugs and should be reported.

TargetUnavailable

The target is unavailable. This may mean it is either not in the metadata or the metadata chain to the target cannot be fully verified.

UnknownHashAlgorithm(String)

There is no known or available hash algorithm.

UnknownKeyType(String)

There is no known or available key type.

VerificationFailure(String)

The metadata or target failed to verify.

LinkGatheringError(String)

PAEParseFailed(String)

RunLibError(String)

AttestationFormatDismatch(String, String)

StringConvertFailed(String)

ArtifactRuleError(String)

Implementations

impl Error

pub fn from_io(err: &Error, path: &Path) -> Error

Helper to include the path that causd the error for FS I/O errors.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<DecodeError> for Error

fn from(err: DecodeError) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(err: Utf8Error) -> Error

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Error

impl StructuralPartialEq for Error
