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.

ExpiredMetadata(Role)

Metadata was expired.

IllegalArgument(String)

An illegal argument was passed into a function.

MissingMetadata(Role)

The metadata was missing, so an operation could not be completed.

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.

UnkonwnHashAlgorithm(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.

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 Eq for Error

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
