pub type TextWidth = Arc<dyn Fn(&str, &Font, bool) -> f32 + Send + Sync>;Expand description
Width in points of one line of text drawn in a cell font, measured by a front end that has
the font the grid draws with. With exact false the front end may answer with a cheaper
measure that is never narrower (AutoFit asks for it on columns with many distinct values).
Commands call it while they run, so a front end must not run commands while holding a lock
the measure takes (egui’s: see theme::cell_text_width in the UI crate).
