Information about an adapter.

Fields

name: String

Adapter name

vendor: u32

Backend-specific vendor ID of the adapter

This generally is a 16-bit PCI vendor ID in the least significant bytes of this field. However, more significant bytes may be non-zero if the backend uses a different representation.

• For Backend::Vulkan, the VkPhysicalDeviceProperties::vendorID is used, which is a superset of PCI IDs.

device: u32

Backend-specific device ID of the adapter

This generally is a 16-bit PCI device ID in the least significant bytes of this field. However, more significant bytes may be non-zero if the backend uses a different representation.

• For Backend::Vulkan, the VkPhysicalDeviceProperties::deviceID is used, which is a superset of PCI IDs.

device_type: DeviceType

Type of device

device_pci_bus_id: String

Backend-specific PCI bus ID of the adapter.

• For Backend::Vulkan, VkPhysicalDevicePCIBusInfoPropertiesEXT is used, if available, in the form bus:device.function, e.g. 0000:01:00.0.

driver: String

Driver name

driver_info: String

Driver info

backend: Backend

Backend used for device

subgroup_min_size: u32

Minimum possible size of a subgroup on this adapter. Will never be lower than crate::MINIMUM_SUBGROUP_MIN_SIZE.

This will vary from device to device. Typical values are listed below.

• NVIDIA: 32
• AMD GCN/Vega: 64
• AMD RDNA+: 32
• Intel: 8 or 16
• Qualcomm: 64
• WARP: 4
• lavapipe: 8

subgroup_max_size: u32

Maximum possible size of a subgroup on this adapter. Will never be higher than crate::MAXIMUM_SUBGROUP_MAX_SIZE.

This will vary from device to device. Typical values are listed below:

• NVIDIA: 32
• AMD GCN/Vega: 64
• AMD RDNA+: 64
• Intel: 16 or 32
• Qualcomm: 128
• WARP: 4 or 128
• lavapipe: 8

transient_saves_memory: bool

If true, adding [TextureUsages::TRANSIENT] to a texture will decrease memory usage.

Trait Implementations

impl Clone for AdapterInfo

fn clone(&self) -> AdapterInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AdapterInfo

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

Formats the value using the given formatter.

impl Hash for AdapterInfo

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AdapterInfo

fn eq(&self, other: &AdapterInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
