Struct PrevPaneState 

Source 
pub struct PrevPaneState {
    pub buffer: BufferKind,
    pub buffer_id: BufferId,
    pub cursor: Position,
    pub scroll: u32,
    pub modal: ModalState,
}
Expand description

Snapshot of the active pane’s state captured just before help took it over. Used by dismiss_popup to restore the user to the buffer + cursor + scroll they came from. The same struct serves both display modes (in-pane and popup-overlay).

Fields§

§buffer: BufferKind§buffer_id: BufferId§cursor: Position§scroll: u32§modal: ModalState

PU-A.1b: the modal state at capture. A focus-stealing popup (PopupFocus::Steal) is a Normal-mode surface — its major mode receives keys — so open sets ModalState::Normal and dismiss restores this, returning a user who was mid-Insert to their prompt in Insert (popup-api.md §5). Passive floats never flip modal, so they never capture a PrevPaneState. In-pane help captures this but is torn down by do_close_pane (which ignores it), so the value is inert there.
