pub fn fill_rect(surface: &mut Surface<'_>, rect: Rect, ch: char, style: Style)Expand description
Fill rect with ch in the given style.
The entire rectangle including corners is overwritten. Kept as a plain
function rather than a widget: there’s no configuration to build up
beyond the two arguments already here, and it’s a building block other
widgets (Panel, Table, Scrollbar) call directly.
