Struct FaultInjector 

pub struct FaultInjector { /* private fields */ }

Fault injector for simulation testing.

TigerStyle:

• Explicit fault registration
• Deterministic through RNG
• Statistics tracked
• Interior mutability for sharing via Arc

Implementations

impl FaultInjector

pub fn new(rng: DeterministicRng) -> Self

Create a new fault injector with the given RNG.

pub fn register(&mut self, config: FaultConfig)

Register a fault configuration.

Note: Registration must happen before sharing via Arc.

pub fn should_inject(&self, operation: &str) -> Option<FaultType>

Check if a fault should be injected for the given operation.

Returns the fault type if one should be injected, None otherwise.

TigerStyle: Uses interior mutability (Mutex) so can be called on &self, allowing FaultInjector to be shared via Arc.

pub fn injection_stats(&self) -> HashMap<String, u64>

Get injection statistics.

pub fn total_injections(&self) -> u64

Get total number of injections.

pub fn reset_stats(&self)

Reset all statistics.

Trait Implementations

impl Debug for FaultInjector

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

Formats the value using the given formatter.
