cuda::experimental::stream_ref

struct stream_ref : public cuda::stream_ref

A non-owning wrapper for cudaStream_t.

Note

It is undefined behavior to use a stream_ref object beyond the lifetime of the stream it was created from, except for the get() member function.

Subclassed by cuda::experimental::stream

Public Types

using scheduler_concept = execution::scheduler_t

Public Functions

stream_ref() = delete

inline constexpr stream_ref(

const ::cuda::stream_ref &__other,

) noexcept

Converting constructor from ::cuda::stream_ref.

Post:

*this == __other

inline bool ready() const

Deprecated. Use is_done() instead.

inline auto schedule() const noexcept

Returns a execution::sender that completes on this stream.

Note

Equivalent to execution::schedule(execution::stream_scheduler{*this}).

inline logical_device logical_device() const

Get the logical device under which this stream was created.

Compared to device() member function the returned logical_device will hold a green context for streams created under one.
