A type to represent the different kinds of errors.

Variants

Io(Error)

There was an error reading from or writing to an external source

Decode(DecodeError)

Data was improperly encoded as base64

Utf8Error(FromUtf8Error)

Data was not a valid UTF8 string.

InvalidCertType(u32)

A certificate type that doesn’t exist was requested. Should be either 1 or 2

InvalidFormat

The format of a certificate or data was incorrect/invalid

UnexpectedEof

The stream ended unexpectedly

NotCertificate

The provided data was not a certificate

KeyTypeMismatch

The requested signature or key was incompatible with what was previously specified or an x509 certificate contains a public key that is not compatible with SSH.

InvalidSignature

The certificate is not signed correctly and invalid

InvalidAllowedSigner(AllowedSignerParsingError)

A parsing error for one allowed signer

InvalidAllowedSigners(AllowedSignerParsingError, usize)

A parsing error for a collection/file of allowed signers

SigningError

A cryptographic operation failed.

EncryptedPrivateKey

An encrypted private key was provided with no decryption key

EncryptedPrivateKeyNotSupported

An encrypted private key was supplied but the encryption method is not supported

UnknownKeyType(String)

The key type is unknown

UnknownCurve(String)

The curve in an ECC public/private key/signature is unknown

ParsingError

A generic parsing error which occurs whenever data sent does not match the expected format

YubikeyPIVError(Error)

An error occured in the yubikey module

FidoError(Error)

An error occured in the FIDO module

Unsupported

This occurs when you try to use a feature that could technically work but is currently unimplemented.

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, f: &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.
