Struct Event 

pub struct Event { /* private fields */ }

A CUDA event.

Implementations

impl Event

pub fn new(context: &Context) -> Result<Self>

Create a new event with default flags (timing enabled).

pub fn no_timing(context: &Context) -> Result<Self>

Create an event optimized for synchronization (no timing).

pub fn with_flags(context: &Context, flags: u32) -> Result<Self>

Create an event with raw flags (see CUevent_flags).

pub fn record(&self, stream: &Stream) -> Result<()>

Record this event on the given stream. The event “happens” when all prior work on stream has completed.

pub fn record_with_flags(&self, stream: &Stream, flags: u32) -> Result<()>

As record but with a raw CUDA event-record flags bitmask. See CU_EVENT_RECORD_* in NVIDIA’s headers.

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

Block the calling host thread until this event has completed.

pub fn is_complete(&self) -> Result<bool>

Ok(true) if the event has completed.

pub fn elapsed_time_ms(start: &Event, end: &Event) -> Result<f32>

Elapsed milliseconds of device work between start (recorded first) and end (recorded later). Both events must have been created with timing enabled.

pub fn context(&self) -> &Context

The Context this event lives in.

pub fn as_raw(&self) -> CUevent

Raw CUevent. Use with care.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Event

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
