Ambiguous definition of TRUSTEE_W

Summary

TRUSTEE_W is defined in the following way in C++:

typedef struct _TRUSTEE_W {
  struct _TRUSTEE_W          *pMultipleTrustee;
  MULTIPLE_TRUSTEE_OPERATION MultipleTrusteeOperation;
  TRUSTEE_FORM               TrusteeForm;
  TRUSTEE_TYPE               TrusteeType;
  union {
    LPWSTR             ptstrName;
    SID                *pSid;
    OBJECTS_AND_SID    *pObjectsAndSid;
    OBJECTS_AND_NAME_W *pObjectsAndName;
  };
  LPWCH                      ptstrName;
} TRUSTEE_W, *PTRUSTEE_W, TRUSTEEW, *PTRUSTEEW;

However the Rust definition only lists the first variant from union:

pub struct TRUSTEE_W {
    pub pMultipleTrustee: *mut TRUSTEE_W,
    pub MultipleTrusteeOperation: MULTIPLE_TRUSTEE_OPERATION,
    pub TrusteeForm: TRUSTEE_FORM,
    pub TrusteeType: TRUSTEE_TYPE,
    pub ptstrName: windows_core::PWSTR,
}

I am not sure what the right solution to this, but I guess either having enum for union or c_void* because otherwise I am forced to wrap, i.e SID into PWSTR to be able to pass the compiler check.

Compare the documented TRUSTEE_W layout with the generated Rust definition shown in the issue, focusing on the union and its supported variants. Determine the correct representation and validate that callers can pass SID and name values without casts; no repository file or test is named in the report.
