Struct wgpu_hal::vulkan::Adapter

pub struct Adapter { /* private fields */ }

Available on vulkan only.

Implementations

impl Adapter

pub fn raw_physical_device(&self) -> PhysicalDevice

pub fn physical_device_capabilities(&self) -> &PhysicalDeviceProperties

pub fn shared_instance(&self) -> &InstanceShared

pub fn required_device_extensions( &self, features: Features, ) -> Vec<&'static CStr>

pub fn physical_device_features( &self, enabled_extensions: &[&'static CStr], features: Features, ) -> PhysicalDeviceFeatures

Create a PhysicalDeviceFeatures for opening a logical device with features from this adapter.

The given enabled_extensions set must include all the extensions selected by required_device_extensions when passed features. Otherwise, the PhysicalDeviceFeatures value may not be able to select all the Vulkan features needed to represent features and this adapter’s characteristics.

Typically, you’d simply call required_device_extensions, and then pass its return value and the feature set you gave it directly to this function. But it’s fine to add more extensions to the list.

pub unsafe fn device_from_raw( &self, raw_device: Device, handle_is_owned: bool, enabled_extensions: &[&'static CStr], features: Features, family_index: u32, queue_index: u32, ) -> Result<OpenDevice<Api>, DeviceError>

Safety

• raw_device must be created from this adapter.
• raw_device must be created using family_index, enabled_extensions and physical_device_features()
• enabled_extensions must be a superset of required_device_extensions().
