Required Methods

fn capabilities(&self) -> DriverCapabilities

fn write(&self, key: &str, data: &[u8]) -> Result<(), StorageError>

fn append(&self, key: &str, data: &[u8]) -> Result<(), StorageError>

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

fn read_range( &self, key: &str, offset: usize, len: usize, ) -> Result<Vec<u8>, StorageError>

fn delete(&self, key: &str) -> Result<(), StorageError>

fn snapshot(&self, snapshot_id: &str) -> Result<(), StorageError>

Create a point-in-time snapshot named snapshot_id. On APFS this calls clonefile(2) and is O(1), zero-cost on disk.

fn flush(&self) -> Result<(), StorageError>

fn prefetch_hint(&self, key: &str)

fn eviction_hint(&self, key: &str)

fn describe(&self) -> &str
