Struct EditingUi 

pub struct EditingUi {
    pub caret: Option<usize>,
    pub selection: Option<(usize, usize)>,
    pub selection_bg: (u8, u8, u8),
    pub selection_fg: (u8, u8, u8),
}

The editing UI to paint into a raster. Offsets are bytes into the spec’s text, on char boundaries; anything out of range or misaligned is dropped rather than panicking, since a stale frontend offset is not worth refusing to draw the heading over.

Fields

caret: Option<usize>

Byte offset the caret bar is drawn at, or None for no caret.

selection: Option<(usize, usize)>

Selected byte range (start, end), or None for no selection.

selection_bg: (u8, u8, u8)

The fill behind selected glyphs. The terminal’s selection is reverse video, so its caller passes the heading’s own ink here…

selection_fg: (u8, u8, u8)

…and something that reads on that fill here, for the glyphs on it (and for the caret whenever it stands inside the selection, where a bar in the ink would sink into a fill of the same color).
