Stream View

#include <raft/core/stream_view.hpp>

namespace raft

static auto const stream_view_per_thread = stream_view{}

struct stream_view

#include <stream_view.hpp>

A lightweight wrapper around rmm::cuda_stream_view that can be used in CUDA-free builds

While CUDA-free builds should never actually make use of a CUDA stream at runtime, it is sometimes useful to have a symbol that can stand in place of a CUDA stream to avoid excessive ifdef directives interspersed with other logic. This struct’s methods invoke the underlying rmm::cuda_stream_view in CUDA-enabled builds but throw runtime exceptions if any non-trivial method is called from a CUDA-free build
