Trait Implementations

impl<S> AsyncManifestStore for OwnedAsyncTransactionOverlayStore<S>

where S: AsyncStore + AsyncManifestStore, <S as AsyncManifestStore>::Error: Send + Sync,

type Error = TransactionOverlayError

Error type for manifest operations.

async fn get_root( &self, name: &[u8], ) -> Result<Option<RootManifest>, Self::Error>

Load a named root manifest.

async fn put_root( &self, name: &[u8], manifest: &RootManifest, ) -> Result<(), Self::Error>

Unconditionally insert or replace a named root manifest.

async fn delete_root(&self, name: &[u8]) -> Result<(), Self::Error>

Delete a named root manifest. Deleting a missing name is not an error.

async fn compare_and_swap_root( &self, name: &[u8], expected: Option<&RootManifest>, new: Option<&RootManifest>, ) -> Result<ManifestUpdate, Self::Error>

Atomically update a named root if the current manifest matches expected.

impl<S> AsyncStore for OwnedAsyncTransactionOverlayStore<S>

where S: AsyncStore, S::Error: Send + Sync,

type Error = TransactionOverlayError

Error type for storage operations.

async fn get(&self, key: &[u8]) -> Result<Option<Vec<u8>>, Self::Error>

Get value by key.

async fn put(&self, key: &[u8], value: &[u8]) -> Result<(), Self::Error>

Store key-value pair.

async fn delete(&self, key: &[u8]) -> Result<(), Self::Error>

Delete key.

Publish canonical immutable nodes with advisory logical context.

async fn batch_get_ordered( &self, keys: &[&[u8]], ) -> Result<Vec<Option<Vec<u8>>>, Self::Error>

Retrieve multiple keys while preserving request order.

fn prefers_batch_reads(&self) -> bool

Whether this store has an efficient native batched-read implementation.

fn read_parallelism(&self) -> usize

Maximum in-flight point reads for default ordered batch reads.

async fn get_shared(&self, key: &[u8]) -> Result<Option<Arc<[u8]>>, Self::Error>

Async immutable shared-byte read.

async fn batch_get_shared_ordered_unique( &self, keys: &[&[u8]], ) -> Result<Vec<Option<Arc<[u8]>>>, Self::Error>

fn has_native_shared_reads(&self) -> bool

Whether async shared reads retain backend-owned immutable allocations.

async fn batch_get( &self, keys: &[&[u8]], ) -> Result<HashMap<Vec<u8>, Vec<u8>>, Self::Error>

Retrieve multiple keys as a map.

async fn batch_get_ordered_unique( &self, keys: &[&[u8]], ) -> Result<Vec<Option<Vec<u8>>>, Self::Error>

Retrieve unique keys in request order.

async fn batch_put(&self, entries: &[(&[u8], &[u8])]) -> Result<(), Self::Error>

Store multiple key-value pairs.

fn supports_hints(&self) -> bool

Whether this store persists performance hints.

fn prefers_rightmost_path_hints(&self) -> bool

Whether append-heavy writes should maintain the engine’s rightmost-path hint.

async fn get_hint( &self, namespace: &[u8], key: &[u8], ) -> Result<Option<Vec<u8>>, Self::Error>

Store content-addressed nodes and one hint atomically when supported.

impl<S: Clone> Clone for OwnedAsyncTransactionOverlayStore<S>

fn clone(&self) -> OwnedAsyncTransactionOverlayStore<S>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
