Struct CudaStream 

pub struct CudaStream { /* private fields */ }

Implementations

impl CudaStream

pub fn new_non_blocking() -> Result<Self, CudaError>

Creates a new non-blocking CUDA stream using cudaStreamCreateWithFlags with cudaStreamNonBlocking. Non-blocking streams have no implicit synchronization with the legacy default stream (stream 0).

pub fn as_raw(&self) -> cudaStream_t

Get the raw CUDA stream handle.

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

Synchronize this stream.

pub fn wait(&self, event: &CudaEvent) -> Result<(), CudaError>

Wait for the given event.

pub fn to_host_sync(&self) -> Result<(), CudaError>

Record a per-stream event and synchronize to complete all pending D2H copies. Uses event-based sync rather than cudaStreamSynchronize because this waits only for work up to the event point, allowing future selective sync patterns (e.g., wait for a specific copy without draining the entire stream).

Trait Implementations

impl Debug for CudaStream

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

Formats the value using the given formatter.

impl Drop for CudaStream

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.
