[runlevel5]

Context

Rust does offer tier 2 support for ppc64le architecture however this plugin does not offer an option for this platform.

Changes

• Add a condition check for ppc64le

Fail: Unsupported architecture 😭

Testing

I am able to install rust successfully with this patch on RaptorCS Blackbird with IBM POWER9 v2 8-core box:

$ asdf install rust 1.40.0

    Rust is ready to roll.

The installation was successful!

Consideration

It would be great if other platform than x86 could be tested in Github Actions.

[smorimoto]

Thanks! The code looks good! Yes, it would be nice to be able to test other architectures with GitHub Actions. and that's probably not too hard with custom runners or Docker, but I have not much spare time recently, so at this point I only support x86.

[smorimoto]

Of course, if you want to contribute to it, I will gladly review it!

@imbsky

I've put up a pull request to add @joneslee85! :tada:

[runlevel5]

@imbsky I don't have much exposure to Github Actions so I am unsure how but I know with Travis CI it is very easy to setup build for ppc64le.

[smorimoto]

Oh, they seem to provide a great way around them.
