All document data, held in plain HashMaps behind RefCell for interior mutability. One instance per DbContext, shared by all tables within a transaction scope via &HashMapStore.

Implementations

impl HashMapStore

pub fn new() -> Self

pub fn snapshot(&self) -> HashMapStoreSnapshot

Deep-clone the entire store for savepoint support.

pub fn restore(&self, snap: &HashMapStoreSnapshot)

Restore from a savepoint snapshot.

pub fn create_savepoint(&self) -> u64

Create a savepoint by snapshotting the entire store. Returns a savepoint id.

pub fn restore_savepoint(&self, savepoint_id: u64)

Restore the store to a previously created savepoint.

pub fn restore_without_counters(&self, snap: &HashMapStoreSnapshot)

Restore entity and junction data but preserve current counters. Used for undo snapshots where IDs must remain monotonically increasing.

pub fn store_snapshot(&self) -> StoreSnapshot

Create a type-erased store snapshot for undo.

pub fn restore_store_snapshot(&self, snap: &StoreSnapshot)

Restore from a type-erased store snapshot (preserves counters).

Trait Implementations

impl Debug for HashMapStore

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

Formats the value using the given formatter.

impl Default for HashMapStore

fn default() -> HashMapStore

Returns the “default value” for a type.
