Struct DiffViewLayout 

pub struct DiffViewLayout {
    pub visible_rows: usize,
    pub total_rows: usize,
}

Layout information returned by draw_diff_view.

Used by AppLogic to clamp scroll offsets after a resize.

Fields

visible_rows: usize

Number of content rows that fit on screen (after the optional header row).

total_rows: usize

Total number of display lines the backend used for rendering.

In side-by-side mode this equals DiffView::total_rows() (one display line per DiffRow).

In unified mode each hunk contributes an extra @@ … @@ header line, so total_rows = view.total_rows() + hunk_count. Always use this field — not DiffView::total_rows() — when clamping scroll:

view.scroll_offset = view.scroll_offset
    .min(layout.total_rows.saturating_sub(layout.visible_rows));
