Fields

rope: RwLock<Rope>

roots: RwLock<HashMap<EntityId, Root>>

documents: RwLock<HashMap<EntityId, Document>>

frames: RwLock<HashMap<EntityId, Frame>>

blocks: RwLock<HashMap<EntityId, Block>>

lists: RwLock<HashMap<EntityId, List>>

resources: RwLock<HashMap<EntityId, Resource>>

tables: RwLock<HashMap<EntityId, Table>>

table_cells: RwLock<HashMap<EntityId, TableCell>>

format_runs: RwLock<HashMap<EntityId, Vec<FormatRun>>>

block_images: RwLock<HashMap<EntityId, Vec<ImageAnchor>>>

block_footnote_refs: RwLock<HashMap<EntityId, Vec<FootnoteRefAnchor>>>

Footnote references anchored in each block, byte-ordered.

Beside block_images rather than merged with it: the two are written by different editing paths and read together only through format_runs::block_anchors, which is the one place their interleaving is decided.

footnote_markers: RwLock<HashMap<String, String>>

Host-supplied markers by footnote label — what a reference prints.

Ambient and presentation-only, like a syntax highlighter: never serialised, never part of the document, and consulted when a reference is rendered.

It exists because the number is a fact about the host’s manuscript, not about this document. Skribisto compiles one chapter into a document of its own, and that document’s reading order would number the chapter’s notes from one — disagreeing with the badge the writer sees in the editor, for the same note, at the same moment. Empty means “number them yourself”, which is the right answer for a document that is the whole text.

block_offsets: RwLock<BlockOffsetIndex>

counters: RwLock<HashMap<String, EntityId>>

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.
