Check bits order inside structures

[wendelscardua]

  static const constexpr struct {
    bool display_unicorn : 1;
    bool display_polyomino : 1;
    u8 duration : 6;
  } 

In this case, how are these members stored on the byte ? I'd like duration to be the lowest 6 bits, to avoid shifting

yeah, I want the opposite; the fields are ordered from the lowest to highest
