Struct BackupStore 

pub struct BackupStore { /* private fields */ }

Per-file undo store backed by an in-memory stack.

Keys are canonical paths (resolved via std::fs::canonicalize with fallback to cleaned relative path). Each file maps to a stack of BackupEntry values ordered oldest-first so restore_latest pops from the end.

Implementations

impl BackupStore

pub fn new() -> Self

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

Snapshot the current contents of path with a description.

Returns the generated backup ID. Fails with FileNotFound if the file cannot be read.

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

Pop the most recent backup for path and restore the file contents.

Returns the restored entry. Fails with NoUndoHistory if no backups exist for the path.

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

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

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

Return all files that have at least one backup entry.
