Struct DeviceBuilder 

pub struct DeviceBuilder { /* private fields */ }

Implementations

impl DeviceBuilder

pub fn new( physical_device: PhysicalDevice, instance: Arc<Instance>, ) -> DeviceBuilder

pub fn allocation_callbacks( self, allocation_callbacks: AllocationCallbacks, ) -> Self

pub fn build(self) -> Result<Device>

Create a logical Device from the configured PhysicalDevice.

What this does:

• Builds queue create infos for each discovered queue family (default priority 1.0).
• Enables any device extensions that were marked on the PhysicalDevice (and the VK_KHR_swapchain extension when a surface is present or surface init is deferred).
• Pushes a vk::PhysicalDeviceFeatures2 and any requested feature-chain nodes onto the device create pNext chain when the instance supports properties2 or is Vulkan 1.1+.
• Calls vkCreateDevice and returns a Device wrapper on success.

Returns:

• Ok(Device) containing the created vulkanalia::Device, retained Instance and selected PhysicalDevice information.
• An error if device creation fails.

Notes:

• Queue configuration is simplified: every queue family discovered by the physical device is created with a single queue at priority 1.0. Customize if you need different priorities or explicit queue counts.
• Any allocation callbacks previously set via DeviceBuilder::allocation_callbacks are forwarded to vkCreateDevice and stored in the returned Device.
