[Backport] Add stream__wrapper test to thrust by alliepiper · Pull Request #4492 · NVIDIA/cccl

alliepiper · 2025-04-17T18:38:30Z

Add test to ensure that stream wrappers work with thrust::device.on.

* Use `cudaStream_t` for `thrust::device.on(...)`. This was recently switched to use `cuda::stream_ref`, which broke users that have their own custom stream wrappers (nvbench, rmm, probably others). There's no real benefit to using a stream_ref here, and it breaks existing implicit conversions. * Add test to ensure that stream wrappers work with thrust::device.on
