ludus::platform::HostedSurfaceImages¶

Struct

The images of one hosted surface generation.

A generation is a fixed extent and format. The producer allocates a new generation whenever its extent changes; image indices are 0 to HOSTED_SURFACE_IMAGE_COUNT - 1 within a generation.

DeviceUuid¶

foundation::StaticArray<foundation::uint8, HOSTED_ADAPTER_UUID_BYTES> ludus::platform::HostedSurfaceImages::DeviceUuid {}

Vulkan only: the producer's VkPhysicalDeviceIDProperties::deviceUUID. Zero on macOS.

Declared in modules/platform/include/ludus/platform/hosted_surface.h

DriverUuid¶

foundation::StaticArray<foundation::uint8, HOSTED_ADAPTER_UUID_BYTES> ludus::platform::HostedSurfaceImages::DriverUuid {}

Vulkan only: the producer's VkPhysicalDeviceIDProperties::driverUUID. Zero on macOS.

Handles¶

foundation::StaticArray<HostedImageHandle, HOSTED_SURFACE_IMAGE_COUNT> ludus::platform::HostedSurfaceImages::Handles {}
