Struct opencl_core::command_queue::CommandQueue

pub struct CommandQueue { /* fields omitted */ }

Methods

impl CommandQueue

pub fn create(
    context: &Context,
    device: &Device,
    opt_props: Option<CommandQueueProperties>
) -> Output<CommandQueue>

Creates a new CommandQueue with the given Context on the given Device.

pub fn create_copy(&self) -> Output<CommandQueue>

Creates a new copy of a CommandQueue with CommandQueue's Context on the CommandQueue's Device.

This function is useful for executing concurrent operations on a device within the same Context.

pub fn low_level_context(&self) -> ClContext

The low-level context of the CommandQueue

pub fn low_level_device(&self) -> ClDeviceID

pub fn write_buffer<T: ClNumber>(
    &self,
    device_buffer: &Buffer,
    host_buffer: &[T],
    opts: Option<CommandQueueOptions>
) -> Output<()>

write_buffer is used to move data from the host buffer (buffer: &[T]) to the OpenCL cl_mem pointer inside d_mem: &Buffer<T>.

pub fn read_buffer<T: ClNumber>(
    &self,
    device_buffer: &Buffer,
    host_buffer: &mut [T],
    opts: Option<CommandQueueOptions>
) -> Output<Option<Vec<T>>>

read_buffer is used to move data from the device_mem (cl_mem pointer inside &DeviceMem<T>) into a host_buffer (&mut [T]).

pub fn enqueue_kernel(
    &self,
    kernel: Kernel,
    work: &Work,
    opts: Option<CommandQueueOptions>
) -> Output<()>

pub fn finish(&self) -> Output<()>

pub fn reference_count(&self) -> Output<u32>

pub fn properties(&self) -> Output<CommandQueueProperties>
