Struct MemoryStorage 

pub struct MemoryStorage { /* private fields */ }

In-memory storage backend for tests and synthetic tools.

Implementations

impl MemoryStorage

pub fn new() -> Self

Creates a new value.

Trait Implementations

impl Clone for MemoryStorage

fn clone(&self) -> MemoryStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryStorage

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

Formats the value using the given formatter.

impl Default for MemoryStorage

fn default() -> MemoryStorage

Returns the “default value” for a type.

impl WorldStorage for MemoryStorage

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

Looks up a raw value by exact key.

fn get_many(&self, keys: &[Bytes]) -> Result<Vec<Option<Bytes>>>

Looks up raw values by exact key, preserving input order.

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

Writes a raw key/value pair.

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

Deletes a raw key.

fn for_each_key( &self, options: StorageReadOptions, visitor: &mut (dyn FnMut(&[u8]) -> Result<StorageVisitorControl> + Send), ) -> Result<StorageScanOutcome>

Visits keys without forcing value materialization when the backend can support key-only scans.

fn for_each_prefix( &self, prefix: &[u8], options: StorageReadOptions, visitor: &mut (dyn FnMut(&[u8], &Bytes) -> Result<StorageVisitorControl> + Send), ) -> Result<StorageScanOutcome>

Visits key/value records whose key starts with prefix.

fn for_each_prefix_key( &self, prefix: &[u8], options: StorageReadOptions, visitor: &mut (dyn FnMut(&[u8]) -> Result<StorageVisitorControl> + Send), ) -> Result<StorageScanOutcome>

Visits keys whose key starts with prefix without requiring value materialization when the backend can support key-only scans.

fn write_batch(&self, batch: &StorageBatch) -> Result<()>

Applies a batch of raw operations atomically when supported by the backend.

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

Flushes pending writes to durable storage when supported by the backend.

fn get_many_ordered_with_control( &self, keys: &[Bytes], options: StorageReadOptions, ) -> Result<Vec<Option<Bytes>>>

Looks up raw values by exact key with read options and cancellation, preserving input order.

fn for_each_prefix_ref( &self, prefix: &[u8], options: StorageReadOptions, visitor: &mut (dyn FnMut(StorageEntryRef<'_>) -> Result<StorageVisitorControl> + Send), ) -> Result<StorageScanOutcome>

Visits key/value records as borrowed byte views.

fn for_each_entry( &self, options: StorageReadOptions, visitor: &mut (dyn FnMut(&[u8], &Bytes) -> Result<StorageVisitorControl> + Send), ) -> Result<StorageScanOutcome>

Visits all key/value records.
