Struct FaultEvidence 

pub struct FaultEvidence { /* private fields */ }

Framework evidence about one failed unit of work.

The runtime proves these properties before a policy may accept a skip. The values describe framework bookkeeping only; they carry no item value.

Implementations

impl FaultEvidence

pub const NONE: FaultEvidence

Evidence for a fault whose failed unit is not located.

pub const fn new( located: bool, known_rollback: bool, forward_checkpoint_proof: bool, ) -> FaultEvidence

Constructs complete skip evidence.

pub const fn with_located(self, located: bool) -> FaultEvidence

Records that exactly one failed input or output ordinal is identified.

pub const fn with_known_rollback(self, known_rollback: bool) -> FaultEvidence

Records that the failed work left no visible external effect.

pub const fn with_forward_checkpoint_proof(self, proof: bool) -> FaultEvidence

Records that the reader proved its checkpoint moved past the input.

pub const fn is_located(self) -> bool

Returns whether exactly one failed unit is identified.

pub const fn is_known_rollback(self) -> bool

Returns whether the failed work is known to have been rolled back.

pub const fn has_forward_checkpoint_proof(self) -> bool

Returns whether forward checkpoint progress is proven.

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FaultEvidence

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

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

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