gpu_buffer_handle() [2/2]

MAYAFLUX_API Portal::Graphics::GpuBufferHandle MayaFlux::Buffers::gpu_buffer_handle	(	const VKBufferResources::GenerationSlot &	slot,
		size_t	size_bytes
	)

View a raw back_buffers slot without reading it back.

Parameters

slot	Slot, typically from VKBuffer::get_buffer_resources().back_buffers or a named state accessor such as NetworkGeometryBuffer::read_state_slot().
size_bytes	Byte size of the slot's contents. A slot does not carry its size, so the owning buffer's own accessor supplies it.

Returns

Non-owning handle carrying the slot's Vulkan buffer and host mapping, or an empty handle when the slot's buffer is null.
