Struct FaultInjector 

pub struct FaultInjector { /* private fields */ }

Test-owned, FIFO fault queues indexed by a stable boundary label.

A queued fault is consumed only when Self::check reaches the matching boundary. No fault is implicit, and an empty queue always permits work.

Implementations

impl FaultInjector

pub fn new() -> Self

Creates an empty injector that permits every boundary.

pub fn inject( &self, point: &str, fault: SimulatorFault, ) -> Result<(), FaultPointError>

Queues one fault for the next visit to point.

pub fn inject_at( &self, operation: &str, boundary: ScenarioBoundary, fault: SimulatorFault, ) -> Result<(), FaultPointError>

Queues one fault at a canonical boundary belonging to operation.

pub fn check( &self, point: &str, ) -> Result<Result<(), SimulatorFault>, FaultPointError>

Consumes and returns the next configured fault at point, if any.

pub fn check_at( &self, operation: &str, boundary: ScenarioBoundary, ) -> Result<Result<(), SimulatorFault>, FaultPointError>

Checks the next fault at a canonical boundary belonging to operation.

pub fn has_pending(&self, point: &str) -> Result<bool, FaultPointError>

Returns whether a boundary still has queued faults.
