Enum ReplayDefenseError 

pub enum ReplayDefenseError {
    Replayed,
    Transient(String),
}

Failure modes from a ReplayDefense substrate call.

Two variants — adapters MUST NOT collapse them. Replayed is an attack signal (someone presented the same jti twice within TTL); Transient is an infrastructure signal (substrate unreachable). Audit log routing differs (security incident vs ops alert), and the engine maps each to its own AuthError variant.

Variants

Replayed

The jti hash was already recorded within TTL — replay detected. Engine maps to AuthError::JtiReplayed.

Transient(String)

Substrate transient failure — engine fails closed and maps to AuthError::ReplayCacheUnavailable. The string carries adapter context for ops triage (NOT for the audit log; the log keys off the variant, not the payload).

Trait Implementations

impl Debug for ReplayDefenseError

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

Formats the value using the given formatter.

impl Display for ReplayDefenseError

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

Formats the value using the given formatter.

impl Error for ReplayDefenseError

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>)
