Struct Device 

pub struct Device(/* private fields */);

The Device struct encapsulates a single SYCL device on which kernels can be executed.

The Device struct provides the common reference semantics.

Implementations

impl Device

pub fn get_devices() -> Vec<Self>

Returns a Vec containing all the root devices from all SYCL backends available in the system which have the device type encapsulated by DeviceType.

pub fn get_platform(&self) -> Platform

Returns the associated SYCL platform.

pub fn has(&self, aspect: Aspect) -> bool

Returns whether this device has the requested aspect.

pub fn can_access_peer(&mut self, peer: &Device, value: PeerAccess) -> bool

Queries the peer access status between this device and peer according to the query value.

PeerAccess::AccessSupported: Returns true only if it is possible for this device to enable peer access to USM device memory allocations located on the peer device.

PeerAccess::AtomicsSupported: When this query returns true, it indicates that this device may concurrently access and atomically modify USM device memory allocations located on the peer device when peer access is enabled to that device.

pub fn enable_peer_access(&mut self, peer: &Device) -> Result<()>

Enables this device to access USM device allocations located on the peer device. This does not permit the peer device to access this device’s memory.

Once this access is enabled, SYCL kernel functions and the explicit memory functions may access USM device allocations on the peer device subject to the normal rules about context as described in the core SYCL specification.

pub fn disable_peer_access(&mut self, peer: &Device) -> Result<()>

Disables access to the peer device’s memory from this device.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<&Device> for Queue

fn from(value: &Device) -> Self

Converts to this type from the input type.

impl From<UniquePtr<Device>> for Device

fn from(value: UniquePtr<Device>) -> Self

Converts to this type from the input type.

impl InfoTarget for Device

fn get_info<T: Info<Target = Self>>(&self) -> T::Item

Queries this object for information requested by given generic parameter.
