Enum PowFailureMode 

pub enum PowFailureMode {
    TokenInvalid,
    NonceReplayed,
    Timeout,
    Blocked,
    Captcha,
    Other,
}

Failure mode a PoW solve attempt can end in.

The taxonomy is small and stable — every variant maps to a well-understood terminal state observed by the runner or the T83 challenge feedback loop. The wire label is snake_case and a severity_weight is provided for the scorer (higher = worse for the aggregate score).

Example

use stygian_charon::pow_profile::PowFailureMode;

assert_eq!(PowFailureMode::Captcha.label(), "captcha");
assert!(PowFailureMode::Captcha.severity_weight() > PowFailureMode::Timeout.severity_weight());

Variants

TokenInvalid

The token was rejected as invalid by the vendor.

NonceReplayed

The nonce was already used (replay detected by T91).

Timeout

The solve attempt timed out before completion.

Blocked

The vendor blocked the request outright (403/429).

Captcha

The vendor demanded a captcha the runner cannot solve.

Other

Any other observed failure mode.

Implementations

impl PowFailureMode

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

Stable, lower-case wire label.

pub const fn severity_weight(self) -> f64

Severity weight contributed to the aggregate score (higher = worse). The weights are bounded in [0.0, 1.0] so the failure-severity term in the scorer remains a unit-interval value.

Trait Implementations

impl Clone for PowFailureMode

fn clone(&self) -> PowFailureMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PowFailureMode

impl Debug for PowFailureMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PowFailureMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PowFailureMode

impl Hash for PowFailureMode

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 Ord for PowFailureMode

fn cmp(&self, other: &PowFailureMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PowFailureMode

fn eq(&self, other: &PowFailureMode) -> 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 PartialOrd for PowFailureMode

fn partial_cmp(&self, other: &PowFailureMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PowFailureMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
