Struct RewindStore 

pub struct RewindStore { /* private fields */ }

Session-scoped dirty path tracker + disk-backed rewind store.

Implementations

impl RewindStore

pub fn new( data_dir: impl AsRef<Path>, session_id: &str, project_root: impl AsRef<Path>, ) -> Self

pub fn root(&self) -> &Path

pub fn note_written_paths(&mut self, paths: impl IntoIterator<Item = PathBuf>)

Mark absolute paths as dirty (session lifetime) and turn-written.

pub fn clear_turn_written(&mut self)

Clear per-turn write set (call after capturing a point / finishing turn).

pub fn is_dirty(&self, abs: &Path) -> bool

Whether abs is already tracked as dirty for this session.

pub fn next_prompt_index(&self) -> usize

Count of user turns already recorded (for next prompt_index).

pub fn ensure_pre_write_capture( &mut self, paths: impl IntoIterator<Item = PathBuf>, ) -> Result<()>

Before a write tool mutates disk: snapshot paths not yet in the dirty set into the latest rewind point so restore can undo first-touch edits.

Call this with absolute (or project-relative) paths while the file still has its pre-write content. Marks paths dirty + turn-written.

pub fn capture_point( &mut self, prompt_index: usize, prompt_text: &str, created_at: u64, ) -> Result<RewindPointMeta>

Capture pre-turn state for prompt_index and append to disk.

pub fn finalize_turn_created_paths(&mut self, prompt_index: usize) -> Result<()>

Finalize created_paths for the latest point (paths newly written this turn that did not exist in that point’s pre-snapshot as existing files).

pub fn load_points(&self) -> Vec<RewindPointMeta>

pub fn restore_to(&mut self, prompt_index: usize) -> RestoreSummary

Restore filesystem to pre-turn state of prompt_index, then drop points ≥ index.

Also deletes files first created in turns ≥ prompt_index.

pub fn clear_all(&mut self) -> Result<()>

Remove all rewind data for this session (e.g. on session delete).
