Struct Event 

pub struct Event { /* private fields */ }

A counter command buffers wait on (CommandBuffer::wait_event) and the CPU raises (signal). Waiters for a value run once the counter reaches it.

Implementations

impl Event

pub fn new(device: &Device) -> Result<Self>

A new event on device, at value 0.

pub fn signal(&self, value: u64)

Raises the counter to value, releasing GPU work that waits for it.

pub fn wait(&self, value: u64, timeout: Duration) -> bool

Waits on the CPU until the counter reaches value, for at most timeout; whether it did. Spins briefly first: a collective’s input is usually ready within microseconds.

pub fn value(&self) -> u64

The counter.
