Why do I need Rust to pip install autobahn?

[malibu1966]

I have python 3.6, which is the newest available on RHEL 8. When I try to pip install Autobahn, I now get the following:

            =============================DEBUG ASSISTANCE==========================
            If you are seeing an error here please try the following to
            successfully install cryptography:

            Upgrade to the latest pip and try again. This will fix errors for most
            users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
            =============================DEBUG ASSISTANCE==========================

    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-geq4mmwy/cryptography/setup.py", line 18, in <module>
        from setuptools_rust import RustExtension
    ModuleNotFoundError: No module named 'setuptools_rust'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-geq4mmwy/cryptography/
You are using pip version 9.0.3, however version 25.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Two questions:

1. How do I get around this? I have no experience with Rust.
2. How can I now install Autobahn on AIX, which Rust doesn't work on?

Thank you.

UPDATE: I worked backwards and I find that I can install 18.12.1, but I would prefer to use the latest version obviously.

Important libraries in Python such as Cryptography now depend on Rust. So there's not a lot Autobahn developers can do about this -- I would ask in more general Python forum such as #python on Libera IRC network.

the latest version requires Cryptography, which requires Rust - so you are on your own unfort.

btw: what's the respective IBM zOS bug for lack of Rust ? a link might help others save time.

apart from that, quick digging turned up a container image that claims Rust (on s360, but under Linux, not Aix) icr.io/ibmz/rust:1.73.0-jammy ? IBM/ibm-z-oss-hub#90

Yeah that is linux on mainframe. Thanks for the mention. I saw some stuff too, but not from official sources. I cannot really consider anything from unofficial sources.

Also, now I'm curious because the latest repository does seem to have rust-setuptools... So maybe that's promising?

I have no idea. Maybe. But yeah, sounds like Rust might be coming ..
