Implementations

impl RopeStore

pub fn new() -> Self

pub fn snapshot(&self) -> RopeStoreSnapshot

O(1) snapshot of the entire store (rope is Arc-shared, all im::HashMaps are HAMT-shared; BlockOffsetIndex is a small Vec cloned outright).

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

Restore from a snapshot. Overwrites counters too — used for transaction rollback (Drop of an uncommitted write txn).

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

Restore everything except counters — used for undo, where IDs must remain monotonically increasing across undo/redo cycles.

pub fn create_savepoint(&self) -> u64

pub fn restore_savepoint(&self, savepoint_id: u64)

pub fn discard_savepoint(&self, savepoint_id: u64)

pub fn store_snapshot(&self) -> StoreSnapshot

Type-erased store snapshot (for the generic undo path).

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

Restore from a type-erased store snapshot (undo semantic — counters preserved).

Trait Implementations

impl Debug for RopeStore

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

Formats the value using the given formatter.

impl Default for RopeStore

fn default() -> RopeStore

Returns the “default value” for a type.
