D does not support bitfields. You can use property methods to get/set
bits. They can later be inlined by the compiler.

struct Testor {
  int data;
  int  small_int(){ return data & 0x1f; }
  void small_int( int val ){ data = val | (data & ~0x1f); }
...
};

Tricks with templates and mixins are also possible.
