Struct BackupStore 

pub struct BackupStore { /* private fields */ }

Per-file undo store with optional disk persistence.

When storage_dir is set, backups persist to disk so undo history survives bridge and OpenCode restarts. Disk layout: <storage_dir>/backups/<path_hash>/meta.json — file path + count <storage_dir>/backups/<path_hash>/0.bak … 19.bak — content snapshots

Implementations

impl BackupStore

pub fn new() -> Self

pub fn set_storage_dir(&mut self, dir: PathBuf)

Set storage directory for disk persistence (called during configure).

pub fn snapshot( &mut self, path: &Path, description: &str, ) -> Result<String, AftError>

Snapshot the current contents of path with a description.

pub fn restore_latest( &mut self, path: &Path, ) -> Result<(BackupEntry, Option<String>), AftError>

Pop the most recent backup for path and restore the file contents. Returns (entry, optional_warning).

pub fn history(&self, path: &Path) -> Vec<BackupEntry>

Return the backup history for a file (oldest first).

pub fn disk_history_count(&self, path: &Path) -> usize

Return the number of on-disk backup entries for a file.

pub fn tracked_files(&self) -> Vec<PathBuf>

Return all files that have at least one backup entry (memory + disk).
