Public Member Functions inherited from xiiHashableStruct< xiiGALExternalMemoryDescription >
constexpr	xiiHashableStruct () noexcept
	Default constructor. Initializes all bytes to zero.

	xiiHashableStruct (const xiiHashableStruct &other) noexcept
	Bitwise copy constructor.

xiiHashableStruct &	operator= (const xiiHashableStruct &other) noexcept
	Bitwise assignment operator.

bool	operator== (const xiiHashableStruct &other) const noexcept
	Compares equality via raw byte comparison.

std::strong_ordering	operator<=> (const xiiHashableStruct &other) const noexcept
	Compares ordering via raw byte comparison.

xiiUInt32	CalculateHash () const noexcept
	Calculates a 32-bit hash from raw bytes of the struct.

void	Clear () noexcept
	Fills all bytes with zero.

bool	IsZero () const noexcept
	Returns true if all bytes are zero.

Public Attributes
xiiBitflags< xiiGALExternalMemoryKind >	m_Type = xiiGALExternalMemoryKind::None
	The type of external memory handle.

xiiBitflags< xiiGALExternalMemoryFlags >	m_Flags = xiiGALExternalMemoryFlags::None
	The usage flags for the external memory.

xiiUInt64	m_uiNativeHandle = 0U
	Native external memory handle (e.g., HANDLE on Windows, file descriptor on Linux).

xiiUInt64	m_uiSize = 0U
	Size of the external memory in bytes.

xiiUInt64	m_uiProcessId = 0U
	Process ID of the process that created the external memory handle. This is used for cross-process memory sharing.

xiiUInt32	m_uiMemoryTypeIndex = 0U
	Memory type index that is compatible with the external memory handle. This is used to ensure that the imported memory can be used with the graphics device.

xiiUInt64	m_uiNativeSemaphoreHandle = 0U
	Native external semaphore handle (e.g., HANDLE on Windows, file descriptor on Linux). Used when importing semaphores for synchronization.

Detailed Description

This describes the external memory description.

Used to import external memory handles into the graphics device. This is useful for interop scenarios where memory is shared between different APIs or processes.
