Struct OwnedTransactionOverlayStore 

pub struct OwnedTransactionOverlayStore<S> { /* private fields */ }

Owned store overlay used by OwnedProllyTransaction.

Trait Implementations

impl<S: Clone> Clone for OwnedTransactionOverlayStore<S>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S> ManifestStore for OwnedTransactionOverlayStore<S>

where S: Store + ManifestStore,

type Error = TransactionOverlayError

Error type for manifest operations.

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

Load a named root manifest.

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

Unconditionally insert or replace a named root manifest.

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

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

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> Store for OwnedTransactionOverlayStore<S>

where S: Store,

type Error = TransactionOverlayError

Error type for storage operations

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

Get value by key

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

Store key-value pair

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

Delete key

fn batch(&self, ops: &[BatchOp<'_>]) -> Result<(), Self::Error>

Batch write operations (atomic if supported by backend)

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

Retrieve multiple keys in a single operation

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

Retrieve multiple keys in a single operation with order preservation

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

Retrieve unique keys in input order.

fn prefers_batch_reads(&self) -> bool

Whether this store has an efficient batched-read implementation.

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

Store multiple key-value pairs in a single operation

fn supports_hints(&self) -> bool

Whether this store persists performance hints.

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

Retrieve an optional performance hint for a logical namespace and key.

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

Persist an optional performance hint for a logical namespace and key.

fn batch_put_with_hint( &self, entries: &[(&[u8], &[u8])], namespace: &[u8], key: &[u8], value: &[u8], ) -> Result<(), Self::Error>

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