Enum AuthError 

#[non_exhaustive]
pub enum AuthError {
    Missing,
    Malformed,
    Rejected(String),
}

Failure cases for authentication.

Missing and Malformed describe transport-level rejections (no header / wrong scheme); Rejected carries an authenticator-supplied diagnostic string that MUST stay server-side — handlers map this to a JSON-RPC -32001 Unauthenticated envelope on the wire without echoing the inner message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Missing

The Authorization header was not present on the request.

Malformed

The header is present but does not match the expected format (e.g. wrong scheme prefix).

Rejected(String)

The verifier rejected the credential (bad signature, expired token, revoked, etc.). The string is included for log diagnostics and never returned to the caller.

Trait Implementations

impl Debug for AuthError

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

Formats the value using the given formatter.

impl Display for AuthError

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

Formats the value using the given formatter.

impl Error for AuthError

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>)
