Function create_device 

Source 
pub unsafe fn create_device(
    instance: &Instance,
    physical_device: PhysicalDevice,
    create_info: &DeviceCreateInfo,
    allocator: Option<&AllocationCallbacks>,
) -> Result<Device, CallError>
Expand description

Create a logical device from a physical device.

§Errors

Reports preflight/metadata failures, driver errors, invalid native outputs and unavailable destruction. If rollback is impossible, CallError::InitializationFailed retains the device for explicit recovery.

§Safety

The create info, its reachable pointers and allocator callbacks must meet Vulkan valid usage. Allocator state must remain alive until destruction.
