Struct rust_gpu_tools::Device

pub struct Device { /* private fields */ }

A device that may have a CUDA and/or OpenCL GPU associated with it.

Implementations

impl Device

pub fn vendor(&self) -> Vendor

Returns the Vendor of the GPU.

pub fn name(&self) -> String

Returns the name of the GPU, e.g. “GeForce RTX 3090”.

pub fn memory(&self) -> u64

Returns the memory of the GPU in bytes.

pub fn compute_units(&self) -> u32

Returns the number of compute units of the GPU.

pub fn compute_capability(&self) -> Option<(u32, u32)>

Returns the major and minor version of the compute capability (only available on Nvidia GPUs).

pub fn unique_id(&self) -> UniqueId

Returns the best possible unique identifier, a UUID is preferred over a PCI ID.

pub fn framework(&self) -> Framework

Returns the preferred framework (CUDA or OpenCL) to use.

CUDA will be be preferred over OpenCL. The returned framework will work on the device. E.g. it won’t return Framework::Cuda for an AMD device.

pub fn cuda_device(&self) -> Option<&Device>

Returns the underlying CUDA device if it is available.

pub fn opencl_device(&self) -> Option<&Device>

Returns the underlying OpenCL device if it is available.

pub fn all() -> Vec<&'static Device>

Returns all available GPUs that are supported.

pub fn by_pci_id(pci_id: PciId) -> Option<&'static Device>

Returns the device matching the PCI ID if there is one.

pub fn by_uuid(uuid: DeviceUuid) -> Option<&'static Device>

Returns the device matching the UUID if there is one.

pub fn by_unique_id(unique_id: UniqueId) -> Option<&'static Device>

Returns the device matching the unique ID if there is one.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Device

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Device

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

Formats the value using the given formatter.

impl Hash for Device

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl PartialEq<Device> for Device

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
