Struct Event 

pub struct Event { /* private fields */ }

An OpenCL event object.

Has methods to return information from calls to clGetEventInfo and clGetEventProfilingInfo with the appropriate parameters.
Implements the Drop trait to call release_event when the object is dropped.

Implementations

impl Event

pub const fn new(event: cl_event) -> Self

Create an Event from an OpenCL cl_event.

• event - a valid OpenCL cl_event.

returns the new Event

pub const fn get(&self) -> cl_event

Get the underlying OpenCL cl_event.

pub fn wait(&self) -> Result<()>

Wait for the event to complete.

pub fn command_execution_status(&self) -> Result<CommandExecutionStatus>

pub fn command_type(&self) -> Result<EventCommandType>

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

pub fn command_queue(&self) -> Result<cl_command_queue>

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

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

Get data about an OpenCL event. Calls clGetEventInfo to get the desired data about the event.

pub fn set_callback( &self, command_exec_callback_type: cl_int, pfn_notify: extern "C" fn(cl_event, cl_int, *mut c_void), user_data: *mut c_void, ) -> Result<()>

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

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

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

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

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

CL_VERSION_2_0

pub fn profiling_data(&self, param_name: cl_profiling_info) -> Result<Vec<u8>>

Get profiling data about an OpenCL event. Calls clGetEventProfilingInfo to get the desired profiling data about the event.
