write_state_slot()

VKBufferResources::GenerationSlot MayaFlux::Buffers::NetworkGeometryBuffer::write_state_slot

(

const std::string &

name

)

const

Full back_buffers slot a stage should write the named state field to.

Returns

The slot, or a default-constructed (null-handle) slot if undeclared. Equals read_state_slot() for single-slot fields.

Same resolution as write_state_handle, without narrowing to just the Vulkan handle: a CPU-side upload through StagingUtils::upload_back_buffer needs the whole slot (it checks mapped_ptr for the host-visible fast path), not only .buffer.
