Struct ocl::Device

pub struct Device(_);

A device identifier.

Methods

impl Device

fn first(platform: Platform) -> Device

Returns the first available device on a platform

fn specifier() -> DeviceSpecifier

Returns a DeviceSpecifier useful for precisely specifying a set of devices.

fn resolve_idxs(idxs: &[usize], devices: &[Device]) -> OclResult<Vec<Device>>

Resolves a list of indices into a list of valid devices.

devices is the set of all indexable devices.

Errors

All indices in idxs must be valid. Use resolve_idxs_wrap for index lists which may contain out of bounds indices.

fn resolve_idxs_wrap(idxs: &[usize], devices: &[Device]) -> Vec<Device>

Resolves a list of indices into a list of valid devices.

devices is the set of all indexable devices.

Wraps indices around using modulo (%) so that every index is valid.

fn list(platform: &Platform, device_types: Option<DeviceType>) -> Vec<Device>

Returns a list of all devices avaliable for a given platform which optionally match the flags set in the bitfield, device_types.

Setting device_types to None will return a list of all avaliable devices for platform regardless of type.

fn list_all(platform: &Platform) -> Vec<Device>

Returns a list of all devices avaliable for a given platform.

Equivalent to ::list(platform, None).

fn list_select(platform: &Platform, device_types: Option<DeviceType>, idxs: &[usize]) -> OclResult<Vec<Device>>

Returns a list of devices filtered by type then selected using a list of indices.

Errors

All indices in idxs must be valid.

fn list_select_wrap(platform: &Platform, device_types: Option<DeviceType>, idxs: &[usize]) -> Vec<Device>

Returns a list of devices filtered by type then selected using a wrapping list of indices.

Wraps indices around (%) so that every index is valid.

fn list_from_core(devices: Vec<DeviceIdCore>) -> Vec<Device>

Returns a list of Devices from a list of DeviceIdCores

fn name(&self) -> String

Returns the device name.

fn vendor(&self) -> String

Returns the device vendor as a string.

fn max_wg_size(&self) -> usize

Returns the maximum workgroup size.

fn info(&self, info_kind: DeviceInfo) -> DeviceInfoResult

Returns info about the device.

fn to_string(&self) -> String

Returns a string containing a formatted list of device properties.

fn as_core(&self) -> &DeviceIdCore

Returns the underlying DeviceIdCore.

Methods from Deref<Target=DeviceIdCore>

unsafe fn as_ptr(&self) -> cl_device_id

Returns a pointer.
