Enum JwtError 

pub enum JwtError {
    MissingToken,
    InvalidHeader,
    MalformedToken,
    DeserializationFailed,
    InvalidSignature,
    Expired,
    NotYetValid,
    InvalidIssuer,
    InvalidAudience,
    AlgorithmMismatch,
    SigningFailed,
    SerializationFailed,
}

Typed JWT error enum. Stored as modo::Error source via chain().

Use error.source_as::<JwtError>() before the response pipeline or error.error_code() after IntoResponse to identify the failure.

Error identity pattern

use modo::auth::session::jwt::JwtError;

let err = modo::Error::unauthorized("unauthorized")
    .chain(JwtError::Expired)
    .with_code(JwtError::Expired.code());

// Before IntoResponse:
assert_eq!(err.source_as::<JwtError>(), Some(&JwtError::Expired));
// After IntoResponse (in error handler):
assert_eq!(err.error_code(), Some("jwt:expired"));

Variants

MissingToken

No token was found by any configured TokenSource.

InvalidHeader

The token header could not be decoded or parsed.

MalformedToken

The token does not have the expected three-part structure.

DeserializationFailed

The token payload could not be deserialized into the target claims type.

InvalidSignature

The token signature does not match the signing key.

Expired

The token has expired (exp is in the past, beyond leeway).

NotYetValid

The token is not yet valid (nbf is in the future, beyond leeway).

InvalidIssuer

The iss claim does not match the required issuer.

InvalidAudience

The aud claim does not match the required audience.

AlgorithmMismatch

The token header specifies an algorithm that differs from the verifier’s algorithm.

SigningFailed

The HMAC signing operation failed.

SerializationFailed

The claims could not be serialized to JSON.

Implementations

impl JwtError

pub fn code(&self) -> &'static str

Returns a static error code string for use with Error::with_code().

Survives the IntoResponse → Clone → error handler pipeline where the original source is dropped.

Trait Implementations

impl Clone for JwtError

fn clone(&self) -> JwtError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JwtError

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

Formats the value using the given formatter.

impl Display for JwtError

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

Formats the value using the given formatter.

impl Error for JwtError

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 PartialEq for JwtError

fn eq(&self, other: &JwtError) -> 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.
