Struct ccthw_ash_instance::LogicalDevice

pub struct LogicalDevice { /* private fields */ }

The logical device and information about the backing physical device.

Basically everything done with Vulkan requires a logical device. This type helps with the creation of the logical device and keeps the relevant information about the underlying physical device at hand for debugging and referenc.

Implementations

impl LogicalDevice

pub fn physical_device(&self) -> &PhysicalDevice

Get the physical device being controlled by this logical device.

pub fn active_physical_device_extensions(&self) -> &[String]

Get all of the device extensions used when creating the device.

pub unsafe fn new( instance: &VulkanInstance, physical_device: PhysicalDevice, physical_device_extensions: &[String], queue_family_infos: &[QueueFamilyInfo] ) -> InstanceResult<Self>

Create a logical device for interfacing with a given physical device.

Params

• instance - the Vulkan instance which provides access to the physical device.
• physical_device - the actual physical device which this logical device will control.
• physical_device_extensions - the extentions to enable for the physical device.
• queue_family_infos - a slice of structs which control how many device queues to create.

Safety

Unsafe because the logical device must be dropped before the instance used to create it.

Trait Implementations

impl Debug for LogicalDevice

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LogicalDevice

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for LogicalDevice

fn drop(&mut self)

Destroy the logical device.

Safety

Unsafe because:

• The logical device must be dropped before the instance is destroyed.

impl VulkanHandle for LogicalDevice

type Handle = Device

unsafe fn raw(&self) -> &Self::Handle

Get the raw resource handle.
