> IIUC docstest checks this, right?
Correct. Though you do not see `tensor.pxi` listed in the doctest ouput, you would see the error under `lib.pyx` (if there would be any error), here:
https://github.com/apache/arrow/actions/runs/21994415489/job/63550273073?pr=49279#step:6:6853.

After merging your PR, Conbench analyzed the 3 benchmarking runs that have been run so far on merge-commit 3c5825b30dbb5a897a903034c12ce6ece664c560.
There were no benchmark performance regressions. 🎉
The [full Conbench report](https://github.com/apache/arrow/runs/66856552167) has more details. It also includes information about 2 possible false positives for unstable benchmarks that are known to sometimes produce them.
