GUID class base struct

A native representation of a Windows GUID (Globally Unique Identifier).

A GUID is a 128-bit value used pervasively by Windows to identify COM interfaces, COM classes (CLSIDs), WinRT types, and various system-defined entities.

This type maps exactly to the Win32 GUID / IID / CLSID structure and is ABI-compatible with all Windows APIs that expect a GUID pointer.

A GUID is composed of:

  • Data1: 32 bits
  • Data2: 16 bits
  • Data3: 16 bits
  • Data4: 8 bytes

These fields together correspond to the canonical textual form: dddddddd-dddd-dddd-dddd-dddddddddddd

When passing GUIDs to Win32 or COM APIs, use toNative to obtain a pointer with the appropriate lifetime.
