Struct Event 

pub struct Event<A: EventApi> { /* private fields */ }

A device event that owns itself: created with timing enabled, released when dropped.

Implementations

impl<A: EventApi> Event<A>

pub fn new() -> Result<Self, DriverError>

Create an event, with timing enabled.

Errors

DriverError when the driver refuses it.

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

Enqueue the timestamp on stream, returning once it is queued.

Errors

DriverError when the stream will not take the event.

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

Block until the device has reached this event.

Errors

DriverError, the fault the wait revealed on the stream.

pub fn wait_async(&self, stream: A::Stream) -> Result<(), DriverError>

Make stream wait for this event on the device, without blocking here.

Errors

DriverError when the driver refuses the dependency.

pub fn elapsed(&self, other: &Self) -> Result<Duration, DriverError>

Device time from self to other. Both must have been reached.

Errors

DriverError, including “not ready” when either event has not been reached.

Trait Implementations

impl<A: EventApi> Debug for Event<A>

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

Formats the value using the given formatter.

impl<A: EventApi> Drop for Event<A>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
