Struct krnl::device::Device

pub struct Device { /* private fields */ }

A device.

Devices can be cloned, which is equivalent to Arc::clone().

Devices (other than the host) are unique:

let a = Device::builder().build()?;
let b = Device::builder().build()?;
assert_ne!(a, b);

Implementations

impl Device

pub const fn host() -> Self

The host.

pub fn builder() -> DeviceBuilder

A builder for creating a device.

pub fn is_host(&self) -> bool

Is the host.

pub fn is_device(&self) -> bool

Is a device.

pub fn info(&self) -> Option<&Arc<DeviceInfo>>

Device info.

The host returns None.

pub fn wait(&self) -> Result<(), DeviceLost>

Wait for previous work to finish.

If host, this does nothing.

Operations (like kernel dispatches) executed after this method is called will not block, and will not be waited on.

This is primarily for benchmarking, manual synchronization is unnecessary.

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

Prints Device(index, handle) where handle is a u64 that uniquely identifies the device.

See .info() for printing device info.

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

Formats the value using the given formatter.

impl Default for Device

See Device::host().

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq 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: &Rhs) -> bool

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

impl Eq for Device

impl StructuralPartialEq for Device
