(line int)

// Snippet implements the Source interface method.
func (s *sourceImpl) Snippet(line int) (string, bool) {
	charStart, found := s.findLineOffset(line)
	if !found || s.Len() == 0 {
		return "", false
	}
	charEnd, found := s.findLineOffset(line + 1)
	if found {
		return s.Slice(int(charStart), int(charEnd-1)), true
	}
	return s.Slice(int(charStart), s.Len()), true
}

// findLineOffset returns the offset where the (1-indexed) line begins,
// or false if line doesn't exist.
