Enum AuthError 

#[non_exhaustive]
pub enum AuthError {
    Invalid,
    Expired,
    Unavailable,
}

Why a token did not become a Principal. The first two are the caller’s (401), the last is ours (503): the adapter logs the cause, the API answers the code.

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.

Invalid

Malformed, badly signed, for another issuer or audience, or an unknown session.

Expired

Was valid once: the token or the session expired.

Unavailable

Could not be checked: the provider or the database is unreachable.

impl Eq for AuthError

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

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

Provides type-based access to context intended for error reports.
