Struct ExternalSemaphore 

pub struct ExternalSemaphore { /* private fields */ }

An imported external-semaphore handle. Destroyed on drop.

Implementations

impl ExternalSemaphore

pub unsafe fn import(desc: &CUDA_EXTERNAL_SEMAPHORE_HANDLE_DESC) -> Result<Self>

Import an external-semaphore handle.

Safety

Same discipline as ExternalMemory::import.

pub fn signal_fence_async(&self, value: u64, stream: &Stream) -> Result<()>

Enqueue a signal of fence value value on stream.

pub fn wait_fence_async(&self, value: u64, stream: &Stream) -> Result<()>

Enqueue a wait for fence value value on stream.

pub fn as_raw(&self) -> cudaExternalSemaphore_t
