Struct CudaStream 

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

A CUDA stream handle.

Wraps the raw CUstream handle from the driver API. The stream is not automatically destroyed when dropped — call stream_destroy explicitly or use the stream within its creating context lifetime.

Use CudaStream::DEFAULT to obtain the special legacy-default stream sentinel.

Implementations

impl CudaStream

pub const DEFAULT: Self

The legacy default CUDA stream (cudaStreamDefault = 0).

Operations on the default stream block all other streams in the context.

pub const PER_THREAD: Self

Per-thread default stream (cudaStreamPerThread).

Equivalent to passing cudaStreamPerThread in the Runtime API. The value 0x2 is the canonical sentinel used by the CUDA Runtime.

pub const unsafe fn from_raw(raw: CUstream) -> Self

Construct a CudaStream from a raw driver handle.

Safety

The caller must ensure the handle is valid and not used after the associated context is destroyed.

pub fn raw(self) -> CUstream

Returns the underlying raw CUstream.

pub fn is_default(self) -> bool

Returns true if this is the legacy default stream.

Trait Implementations

impl Clone for CudaStream

fn clone(&self) -> CudaStream

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CudaStream

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

Formats the value using the given formatter.

impl Hash for CudaStream

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CudaStream

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
