Struct opencv::core::Device

pub struct Device { /* private fields */ }

Implementations

impl Device

pub fn default() -> Device

pub unsafe fn new(d: *mut c_void) -> Result<Device>

pub fn copy(d: &impl DeviceTraitConst) -> Result<Device>

pub fn copy_mut(d: Device) -> Device

pub fn get_default() -> Result<Device>

pub unsafe fn from_handle(d: *mut c_void) -> Result<Device>

Parameters

• d: OpenCL handle (cl_device_id). clRetainDevice() is called on success.

Note: Ownership of the passed device is passed to OpenCV on success. The caller should additionally call clRetainDevice on it if it intends to continue using the device.

Trait Implementations

impl Boxed for Device

unsafe fn from_raw(ptr: <Device as OpenCVFromExtern>::ExternReceive) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> <Device as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> <Device as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.
