pub fn act_note(style: &PieceStyle, act: &Act<'_>) -> Option<Line<'static>>Expand description
The muted line a control’s Act::hint draws as, or None where it has
none.
A terminal has no pointer, so the hover the other two renderers spend a hint
on is not available and is not the thing anyway: what the description says
is that the sentence is true, never that it is hidden. A row under the
control is this renderer’s answer, and it is the same muted row
field gives a field’s note, so the two read alike wherever they land.
Its own function rather than extra lines out of act, because a control
is one Line everywhere it is drawn and a caller laying out a run needs
to know it is placing two things.
