v.to.rast will only write convert labelled objects (points, lines,areas),
so you MUST give at least "dummy" labels to the valid objects before
converting.  You can use v.alabel to label all unlabelled areas, or get
Darrell McCauley's v.llabel to do the same for lines (to save the tedium of
doing it in v.digit).
