All the errors we can encounter while signing/verifying tokens and a couple of custom one for when the token we are trying to verify is invalid

Variants

GenericError(String)

A generic error which is described by the contained string

DecodeError(DecodeError)

Error returned from failed token decoding

ValidationError(ValidationError)

Error returned from failed token validation

JsonError(Error)

Error during the serialization or deserialization of tokens

DecodeBase64(DecodeError)

Error during base64 encoding or decoding

Utf8(Utf8Error)

Error when decoding bytes to UTF8 string

IOError(Error)

Errors related to IO

KeyRejected(KeyRejected)

Key was rejected by Ring

WrongKeyType

Wrong key type was provided for the cryptographic operation

Fields of WrongKeyType

expected: String

Expected type of key

actual: String

Actual type of key

WrongEncryptionOptions

Wrong variant of EncryptionOptions was provided for the encryption operation

Fields of WrongEncryptionOptions

expected: String

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)>

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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
