struct DblRep
{
   mixin(bitfieldString([
     BitFieldDesc(Type.Ulong, "fraction", 23),
     BitFieldDesc(Type.Ushort, "exponent", 8),
     BitFieldDesc(Type.Bool, "sign", 1)
   ]));
}

With macros would look like

struct DblRep
{
   @BitFields
   struct
   {
     @23 ulong fraction;
     @8 ushort exponent;
     @1 bool sign;
   }
}
