Struct FaultInjectingStore 

pub struct FaultInjectingStore { /* private fields */ }

An [ObjectStore] that delays and fails calls according to a FaultPolicy, delegating everything it does not fail to an inner store.

Implementations

impl FaultInjectingStore

pub fn memory() -> Self

A fault-free in-memory store for consistency tests that inject one targeted GET replacement.

pub fn new(inner: Arc<dyn ObjectStore>, policy: FaultPolicy) -> Self

Wrap inner with policy.

pub fn with_get_overwrite(self, replacement: Bytes) -> Self

Overwrite the requested object immediately before each GET.

HEAD calls still report the existing object. This injects a deterministic overwrite between a metadata check and its read, for consistency drills. The write bypasses put faults and uses the inner store’s normal overwrite.

pub fn attempts(&self, op: StoreOp) -> u64

How many calls of class op have reached this store, failed ones included.
