ludus::platform::HostedAdapterIdentity¶

Struct

Identity of the GPU adapter and driver that import a hosted surface.

Vulkan: the consumer's VkPhysicalDeviceIDProperties::deviceUUID and driverUUID. Opaque memory handles import only on an adapter whose two UUIDs both equal the exporter's, so a producer that renders on this adapter can share its images with the consumer. Metal shares IOSurfaces across GPUs and has no adapter identity.
