Struct opencl3::platform::Platform

pub struct Platform { /* private fields */ }

An OpenCL platform id and methods to query it.
The query methods calls clGetPlatformInfo with the relevant param_name, see: Platform Queries.

Implementations

impl Platform

pub fn new(id: cl_platform_id) -> Platform

pub fn id(&self) -> cl_platform_id

Accessor for the underlying platform id.

pub fn get_devices( &self, device_type: cl_device_type ) -> Result<Vec<cl_device_id>>

Get the ids of available devices of the given type on the Platform.

Examples

use opencl3::platform::get_platforms;
use cl3::device::CL_DEVICE_TYPE_GPU;

let platforms = get_platforms().unwrap();
assert!(0 < platforms.len());

// Choose a the first platform
let platform = &platforms[0];
let device_ids = platform.get_devices(CL_DEVICE_TYPE_GPU).unwrap();
println!("CL_DEVICE_TYPE_GPU count: {}", device_ids.len());
assert!(0 < device_ids.len());

pub fn profile(&self) -> Result<String>

The OpenCL profile supported by the Platform, it can be FULL_PROFILE or EMBEDDED_PROFILE.

pub fn version(&self) -> Result<String>

The OpenCL profile version supported by the Platform, e.g. OpenCL 1.2, OpenCL 2.0, OpenCL 2.1, etc.

pub fn name(&self) -> Result<String>

The OpenCL Platform name string.

pub fn vendor(&self) -> Result<String>

The OpenCL Platform vendor string.

pub fn extensions(&self) -> Result<String>

A space separated list of extension names supported by the Platform.

pub fn host_timer_resolution(&self) -> Result<cl_ulong>

The resolution of the host timer in nanoseconds as used by clGetDeviceAndHostTimer.
CL_VERSION_2_1

pub fn numeric_version(&self) -> Result<cl_version>

The detailed (major, minor, patch) version supported by the platform.
CL_VERSION_3_0

pub fn extensions_with_version(&self) -> Result<Vec<cl_name_version>>

An array of description (name and version) structures that lists all the extensions supported by the platform.
CL_VERSION_3_0

pub fn platform_external_memory_import_handle_types_khr( &self ) -> Result<Vec<cl_name_version>>

cl_khr_external_memory

pub fn platform_semaphore_import_handle_types_khr( &self ) -> Result<Vec<cl_name_version>>

cl_khr_external_semaphore

pub fn platform_semaphore_export_handle_types_khr( &self ) -> Result<Vec<cl_name_version>>

cl_khr_external_semaphore

pub fn platform_semaphore_types_khr(&self) -> Result<Vec<cl_name_version>>

cl_khr_semaphore

pub fn get_data(&self, param_name: cl_platform_info) -> Result<Vec<u8>>

Get data about an OpenCL platform. Calls clGetPlatformInfo to get the desired data about the platform.

pub unsafe fn unload_compiler(&self) -> Result<()>

Unload an OpenCL compiler for a platform. CL_VERSION_1_2

Safety

Compiling is unsafe after the compiler has been unloaded.
