pub fn gutter_px(font_size: f32, line_count: u32) -> f32Expand description
The gutter’s width in PIXELS for a buffer of line_count lines.
Uses the same MONO_ADVANCE_RATIO estimate cell_grid does — so the
gutter and the text agree about how wide a column is, and the text starts
exactly where the gutter stops. The column count comes from
escriba_ui::gutter::gutter_width, never restated here: the number of
columns this face RESERVES and the number the shared model PAINTS have to
be the same number, and a second definition is how they stop being.
