Struct ZnsDriver 

pub struct ZnsDriver { /* private fields */ }

Thin overlay over ZnsZoneManager. Data is logically stored via the ZNS zone-append path; a MmapDriver overlay holds small metadata values that don’t need zone-append semantics.

Implementations

impl ZnsDriver

pub fn new<P: AsRef<Path>>(manager: ZnsZoneManager, overlay_dir: P) -> Self

Trait Implementations

impl StorageDriver for ZnsDriver

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
