Struct Kernel 

pub struct Kernel { /* private fields */ }

An OpenCL kernel object.
Implements the Drop trait to call release_kernel when the object is dropped.

Implementations

impl Kernel

pub const fn new(kernel: cl_kernel) -> Self

Create a Kernel from an OpenCL cl_kernel.

• kernel - a valid OpenCL cl_kernel.

returns a Result containing the new Kernel or the error code from the OpenCL C API function to get the number of kernel arguments.

pub const fn get(&self) -> cl_kernel

Get the underlying OpenCL cl_kernel.

pub fn create(program: &Program, name: &str) -> Result<Self>

Create a Kernel from an OpenCL Program.

• program - a built OpenCL Program.
• name - the name of the OpenCL kernel.

returns a Result containing the new Kernel or the error code from the OpenCL C API function to get the number of kernel arguments.

pub unsafe fn set_arg<T>(&self, arg_index: cl_uint, arg: &T) -> Result<()>

Set the argument value for a specific argument of a kernel.

• arg_index - the kernel argument index.
• arg - a reference to the data for the argument at arg_index.

returns an empty Result or the error code from the OpenCL C API function.

Safety

This function is unsafe because the index, size and value must be valid.

pub unsafe fn set_arg_local_buffer( &self, arg_index: cl_uint, size: size_t, ) -> Result<()>

Create a local memory buffer for a specific argument of a kernel.

• arg_index - the kernel argument index.
• size - the size of the local memory buffer in bytes.

returns an empty Result or the error code from the OpenCL C API function.

Safety

This function is unsafe because the index and size must be valid.

pub unsafe fn set_arg_svm_pointer( &self, arg_index: cl_uint, arg_ptr: *const c_void, ) -> Result<()>

Set set a SVM pointer as the argument value for a specific argument of a kernel.

• arg_index - the kernel argument index.
• arg_ptr - the SVM pointer to the data for the argument at arg_index.

returns an empty Result or the error code from the OpenCL C API function.

Safety

This function is unsafe because the index and ptr must be valid.

pub unsafe fn set_exec_info<T>( &self, param_name: cl_kernel_exec_info, param_ptr: *const T, ) -> Result<()>

Pass additional information other than argument values to a kernel.

• param_name - the information to be passed to kernel, see: Kernel Execution Properties.
• param_ptr - pointer to the data for the param_name.

returns an empty Result or the error code from the OpenCL C API function.

Safety

This function is unsafe because the name and ptr must be valid.

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

pub fn num_args(&self) -> Result<cl_uint>

pub fn reference_count(&self) -> Result<cl_uint>

pub fn context(&self) -> Result<cl_context>

pub fn program(&self) -> Result<cl_program>

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

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

Get data about an OpenCL kernel. Calls clGetKernelInfo to get the desired data about the kernel.

pub fn get_arg_address_qualifier(&self, arg_indx: cl_uint) -> Result<cl_uint>

pub fn get_arg_access_qualifier(&self, arg_indx: cl_uint) -> Result<cl_uint>

pub fn get_arg_type_qualifier(&self, arg_indx: cl_uint) -> Result<cl_ulong>

pub fn get_arg_type_name(&self, arg_indx: cl_uint) -> Result<String>

pub fn get_arg_name(&self, arg_indx: cl_uint) -> Result<String>

pub fn get_arg_data( &self, arg_indx: cl_uint, param_name: cl_kernel_arg_access_qualifier, ) -> Result<Vec<u8>>

Get data about arguments of an OpenCL kernel. Calls clGetKernelArgInfo to get the desired data about arguments of the kernel.

pub fn get_work_group_size(&self, device: cl_device_id) -> Result<size_t>

pub fn get_compile_work_group_size( &self, device: cl_device_id, ) -> Result<Vec<size_t>>

pub fn get_local_mem_size(&self, device: cl_device_id) -> Result<cl_ulong>

pub fn get_work_group_size_multiple( &self, device: cl_device_id, ) -> Result<size_t>

pub fn get_private_mem_size(&self, device: cl_device_id) -> Result<cl_ulong>

pub fn get_work_group_data( &self, device: cl_device_id, param_name: cl_kernel_work_group_info, ) -> Result<Vec<u8>>

Get data about work groups of an OpenCL kernel. Calls clGetKernelArgInfo to get the desired data about work groups of the kernel.

pub fn get_kernel_sub_group_info_khr( &self, device: cl_device_id, param_name: cl_kernel_sub_group_info, input_values: &[size_t], ) -> Result<size_t>

pub fn get_kernel_suggested_local_work_size_khr( &self, command_queue: cl_command_queue, work_dim: cl_uint, global_work_offset: *const size_t, global_work_size: *const size_t, ) -> Result<size_t>
