Struct SimStorage 

pub struct SimStorage { /* private fields */ }

Simulated storage for DST testing.

TigerStyle:

• In-memory HashMap storage
• Fault injection at every operation
• Full statistics tracking
• Shared FaultInjector via Arc (Kelpie pattern)

Implementations

impl SimStorage

pub fn new( clock: SimClock, rng: DeterministicRng, faults: Arc<FaultInjector>, ) -> Self

Create a new simulated storage.

TigerStyle: Takes Arc to share with simulation harness.

pub async fn write( &mut self, key: &str, value: &[u8], ) -> Result<(), StorageError>

Write a value to storage.

Errors

Returns error if fault injection triggers a failure.

pub async fn read(&mut self, key: &str) -> Result<Option<Vec<u8>>, StorageError>

Read a value from storage.

Errors

Returns error if fault injection triggers a failure.

pub async fn delete(&mut self, key: &str) -> Result<bool, StorageError>

Delete a value from storage.

Errors

Returns error if fault injection triggers a failure.

pub async fn exists(&mut self, key: &str) -> Result<bool, StorageError>

Check if a key exists.

Errors

Returns error if fault injection triggers a failure.

pub async fn keys( &mut self, prefix: Option<&str>, ) -> Result<Vec<String>, StorageError>

List keys matching a prefix.

Errors

Returns error if fault injection triggers a failure.

pub fn stats(&self) -> StorageStats

Get storage statistics.

pub fn clock(&self) -> &SimClock

Get the clock.

pub fn clock_mut(&mut self) -> &mut SimClock

Get mutable clock.

pub fn clear(&mut self)

Clear all data.

Trait Implementations

impl Debug for SimStorage

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

Formats the value using the given formatter.
