Enum FaultPhase 

#[non_exhaustive]
pub enum FaultPhase {
    Read,
    Process,
    Write,
    Transaction,
    Checkpoint,
    Listener,
    Backoff,
}

The framework phase that produced a fault.

The phase is framework-owned input for classification. It never carries an item value, error payload, or component-private state.

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.

Read

An item reader failed.

Process

An item processor failed.

Write

An item writer failed.

Transaction

A chunk transaction failed to begin, commit, or roll back.

Checkpoint

Checkpoint or execution-context state could not be produced or stored.

Listener

An authoritative listener callback failed or panicked.

Backoff

Cancellable backoff failed or was interrupted.

Implementations

impl FaultPhase

pub const fn is_policy_eligible(self) -> bool

Returns whether a classifier rule may govern this phase.

Listener failures are never retried or skipped in M3.

pub const fn is_skippable(self) -> bool

Returns whether a committed skip can be counted for this phase.

pub const fn allows_commit_safe_skip(self) -> bool

Returns whether the phase can structurally accept a commit-safe skip.

Only read and process faults occur before any external write effect.

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

Returns the stable low-cardinality telemetry name.

pub fn from_durable_name(value: &str) -> Option<FaultPhase>

Returns the phase for one persisted name, rejecting unknown values.

The names are durable fault-state data and are never renamed.

Trait Implementations

impl Clone for FaultPhase

fn clone(&self) -> FaultPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FaultPhase

impl Debug for FaultPhase

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

impl Eq for FaultPhase

impl Hash for FaultPhase

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

impl Ord for FaultPhase

fn cmp(&self, other: &FaultPhase) -> 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,

impl PartialEq for FaultPhase

fn eq(&self, other: &FaultPhase) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FaultPhase

fn partial_cmp(&self, other: &FaultPhase) -> 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.
