Struct MarkSnapshot 

pub struct MarkSnapshot {
    pub local_marks: BTreeMap<char, (usize, usize)>,
    pub jump_back: Vec<(usize, usize)>,
    pub jump_fwd: Vec<(usize, usize)>,
    pub change_last_edit: Option<(usize, usize)>,
    pub change_list: Vec<(usize, usize)>,
    pub change_cursor: Option<usize>,
    pub global_marks: BTreeMap<char, (usize, usize)>,
}

Buffer-scoped “edit coherence” state snapshotted alongside a UndoEntry’s rope so undo/redo can restore marks, not just text.

Positions are plain (row, col) (or (row, col) values keyed by mark char) — no buffer-id tagging needed here even for global_marks, because a MarkSnapshot always belongs to exactly one buffer’s undo stack; the engine is responsible for reattaching its own buffer_id when writing entries back into the session-global marks map (see Editor::restore_marks).

Fields

local_marks: BTreeMap<char, (usize, usize)>

ma-mz local marks (View::marks_cloned).

jump_back: Vec<(usize, usize)>

Back-jumplist (Ctrl-o stack), newest at the back.

jump_fwd: Vec<(usize, usize)>

Forward-jumplist (Ctrl-i stack), newest at the back.

change_last_edit: Option<(usize, usize)>

`. / '. — position of the most recent change.

change_list: Vec<(usize, usize)>

Changelist ring (g; / g,).

change_cursor: Option<usize>

Walk cursor into change_list; None outside a walk.

global_marks: BTreeMap<char, (usize, usize)>

mA-mZ global marks that belong to THIS buffer (bare (row, col) — the buffer-id is implicit, this buffer).
