Some more possibilities:

  \new Staff <<
    \new Voice \relative c'' {
      \voiceOne {
          %% \voiceOne sets Rest.direction to 1, revert it
          \revert Rest.direction
          %% specify staff-position
          \override Rest.staff-position = #0
        r
        c
        r
        d
      }
    }
    \new Voice \relative c'' {
      \voiceTwo {
        s4 a8 a8 s4 b8 b8
      }
    }
