Enum InvalidationKind 

pub enum InvalidationKind {
    Expired,
    NonceMismatch,
    NonceReplayed,
    SessionBindingMiss,
    ContractMissing,
    NotApplicable,
}

Coarse-grained kind tag for InvalidationReason.

The kind is the stable, wire-level enum (snake_case) that downstream consumers (alerting, dashboards, audit log routers) can switch on without inspecting the full InvalidationReason. The full reason carries the diagnostic context (vendor family, challenge class, supplied vs. expected values); the kind is the routing key.

Example

use stygian_charon::token_lifecycle::InvalidationKind;

let k = InvalidationKind::NonceReplayed;
assert_eq!(k.label(), "nonce_replayed");

Variants

Expired

Token TTL elapsed. The InvalidationReason::Expired variant carries the vendor family, challenge class, observed age, and the TTL that was crossed.

NonceMismatch

Submission’s nonce does not match the contract’s nonce. The InvalidationReason::NonceMismatch variant carries both nonces.

NonceReplayed

A single-use nonce was observed more than once. The InvalidationReason::NonceReplayed variant carries the observation count from the nonce book.

SessionBindingMiss

Submission’s session id does not match the contract’s bound_session.

ContractMissing

No contract was supplied alongside the token. The validator returns this when the caller bypasses the contract path.

NotApplicable

The token’s challenge class is not applicable for the supplied vendor family (e.g. Cloudflare is asked to validate a ProofOfWork token — Cloudflare does not issue PoW tokens).

Implementations

impl InvalidationKind

pub const fn label(self) -> &'static str

Stable, lower-case wire label.

Example

use stygian_charon::token_lifecycle::InvalidationKind;

assert_eq!(InvalidationKind::Expired.label(), "expired");
assert_eq!(InvalidationKind::NonceMismatch.label(), "nonce_mismatch");
assert_eq!(InvalidationKind::NonceReplayed.label(), "nonce_replayed");
assert_eq!(InvalidationKind::SessionBindingMiss.label(), "session_binding_miss");
assert_eq!(InvalidationKind::ContractMissing.label(), "contract_missing");
assert_eq!(InvalidationKind::NotApplicable.label(), "not_applicable");

Trait Implementations

impl Clone for InvalidationKind

fn clone(&self) -> InvalidationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidationKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InvalidationKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for InvalidationKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InvalidationKind

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

impl Serialize for InvalidationKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
