Record an operation; empty operations are ignored. Returns its id.

pub fn push(&mut self, entry: UndoEntry)

Put an entry back, e.g. the remainder of a partially failed undo.

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

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

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

pub fn record_renames(&mut self, renames: Vec<(PathBuf, PathBuf)>) -> u64

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

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

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

Remove and return the most recent entry if it can be undone here.

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

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

Entries, oldest first.
