Struct SessionHistory 

pub struct SessionHistory { /* private fields */ }

Undo/redo stacks for a session.

Implementations

impl SessionHistory

pub fn new() -> Self

History capped at DEFAULT_UNDO_DEPTH turns.

pub fn with_depth(depth: usize) -> Self

History keeping at most depth undo entries (0 = unlimited). The oldest entries drop first.

pub fn clear(&mut self)

Forget every entry (new or switched session), keeping the depth cap.

pub fn can_undo(&self) -> bool

pub fn can_redo(&self) -> bool

pub fn exhausted_depth(&self) -> Option<usize>

Some(undo_depth) when nothing is left to undo because the cap dropped older turns, so /undo can say why it stops there.

pub fn push_before_turn( &mut self, messages: &[Message], project_path: &Path, ) -> StashSlot

Capture current messages before a user turn and start git stash create on a background thread. Wait on the returned slot before the turn can edit files, so the stash shows the tree the user had.

pub fn mark_new_files(&mut self, files: Vec<PathBuf>)

Record untracked files created during the last turn (for cleanup on undo).

pub fn undo( &mut self, current_messages: &[Message], project_path: &Path, ) -> Option<Vec<Message>>

Pop undo: returns previous messages. Restores git working tree if possible.

pub fn redo( &mut self, current_messages: &[Message], project_path: &Path, ) -> Option<Vec<Message>>

Pop redo: returns messages after redo. Restores git if possible.
