12683 :: Is this correct for an opaque struct?

• Niminem (orginal) [2025-02-13T07:10:55+01:00] view original

  
  when XR_PTR_SIZE == 8:
    type
      XrInstance_T* {.incompleteStruct.} = object  # Opaque struct
      XrInstance* = ptr XrInstance_T  # Pointer-based handle
  else:
    type XrInstance* = uint64  # Integer-based handle on 32-bit systems
  Run

  I'm supposed to use this pragma for an opaque struct correct?

  If you don't use .header for your wrapper but instead interface to the binary DLL/lib*.so then you don't need .incompleteStruct. And if you use .header you don't need it either. You only need it for certain archaic constructs (RTTI) when you use the object itself rather than a pointer to it.

  Interesting, thanks Araq. I am using the OpenXR DLL so this good to know. Hopefully within the next week we can do interesting VR stuff with Nim ;)
