Struct StreamGuard 

pub struct StreamGuard(/* private fields */);

Keeps a CudaStream alive for the lifetime of an allocation record.

Implementations

impl StreamGuard

pub fn new(stream: CudaStream) -> Self

Methods from Deref<Target = CudaStream>

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 Clone for StreamGuard

fn clone(&self) -> StreamGuard

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamGuard

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

Formats the value using the given formatter.

impl Deref for StreamGuard

type Target = CudaStream

The resulting type after dereferencing.

fn deref(&self) -> &CudaStream

Dereferences the value.

impl Eq for StreamGuard

impl PartialEq for StreamGuard

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
