Enum PublicAuthError 

pub enum PublicAuthError {
    InvalidOrExpired,
    TemporaryProblem,
}

The single public authentication failure response (INV-8, RFC-012 §14.3).

All internal failure states — not found, expired, revoked, already used, purpose mismatch, binding mismatch, scope mismatch — collapse to InvalidOrExpiredCode. This prevents enumeration attacks by ensuring the caller cannot distinguish record existence from expiry from prior use.

Variants

InvalidOrExpired

The credential (code, token, session) was not accepted. The reason is intentionally omitted from this type; internal diagnostics use the richer internal error layer.

TemporaryProblem

A transient storage failure prevented the operation. The credential may or may not have been consumed; the host should not retry automatically.

Trait Implementations

impl Clone for PublicAuthError

fn clone(&self) -> PublicAuthError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PublicAuthError

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

Formats the value using the given formatter.

impl Display for PublicAuthError

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

Formats the value using the given formatter.

impl Eq for PublicAuthError

impl Error for PublicAuthError

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 PublicAuthError

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