pub struct UndoLog { /* private fields */ }

Undo log with configurable maximum depth.

Implementations

impl UndoLog

pub fn new(max_entries: usize) -> Self

Create a new undo log with the specified maximum entries.

pub fn record( &mut self, operation: UndoableOperation, description: impl Into<String>, ) -> u64

Record an operation in the undo log.

Returns the ID assigned to this entry.

pub fn record_move(&mut self, moves: Vec<(PathBuf, PathBuf)>) -> u64

Record a move operation.

pub fn record_copy(&mut self, created: Vec<PathBuf>) -> u64

Record a copy operation.

pub fn record_delete(&mut self, paths: Vec<PathBuf>) -> u64

Record a delete operation.

pub fn record_rename(&mut self, source: PathBuf, new_name: String) -> u64

Record a rename operation.

source is the full original path before the rename. new_name is the new name component (used for the description).

pub fn record_create_file(&mut self, path: PathBuf) -> u64

Record a file creation.

pub fn record_create_directory(&mut self, path: PathBuf) -> u64

Record a directory creation.

pub fn pop(&mut self) -> Option<UndoEntry>

Pop the most recent undoable entry.

Returns None if the log is empty or the back entry cannot be undone. Does NOT drain through non-undoable entries — only examines the back.

pub fn peek(&self) -> Option<&UndoEntry>

Peek at the most recent entry without removing it.

pub fn len(&self) -> usize

Get the number of entries in the log.

pub fn is_empty(&self) -> bool

Check if the log is empty.

pub fn clear(&mut self)

Clear all entries from the log.

pub fn iter(&self) -> impl Iterator<Item = &UndoEntry>

Get an iterator over all entries (oldest first).
