Support for rustc 1.70 and/or control of rust toolchain?

[tshauck]

Hi,

Thanks for providing this resource. I was hoping to publish a rust based R package however I'm running into challenges that a dependency of my rust package clashes with the installed rustc on the builder, so I'm getting:

error: package `half v2.3.1` cannot be built because it requires rustc 1.70, while the currently active rustc version is 1.65.0

half is used by the arrow rust package.

I think there are workarounds, but the selfishly the easiest would be to have the ability to use 1.70, either installed on the builder or the ability to manage w/ rustup.

If there's a different solution you'd recommend, I'd certainly be open to that too. Thanks!

Failed build for context

Hmm we use the ppa from mozilla which again I think is mostly ported from the latest rust on debian which is currently 1.66.

Perhaps we should switch to the upstream rustup although I really wish rust crate authors would make some effort supporting the mainstream stable rust versions out there, instead of requiring a bleeding edge version...

[tshauck]

Ha, I certainly can sympathize with this after the last week of package updates. FWIW, I think it might cultural differences between the communities. E.g. rustup being from the language team and 1.70 being stable vs beta or the nightly build.

If you'd be willing to try putting rustup on runners, I'd certainly be happy to help test.

OK I'll try switching, see if this breaks other packages...

Ok, thanks. I'll give it a look this afternoon (~5 hrs from now) and follow up.

Looks like you may've seen this, but there looks to be an issue that the install process assumes cargo exists on the path, but it does not yet. I've updated the makevars file in my repo to run rustup update which at least locally and on non-r-universe action builds seems to run as expected. I'll check on the r-universe build next time it's triggered.

There seems to be a problem because rustup installs in the user HOME dir, but github-actions overrides the user HOME with a path from the host.

Yerp... seeing 90ec5dfc0882ecbc5c6091f4abd1f42b680aa9a3 🤞... thanks for working on this

[jeroen]

OK this should be fixed. Now your package fails with another problem 😁 https://github.com/r-universe/wheretrue/actions/runs/5490134880/jobs/10007164366

Onward -- thanks!

half is used by the arrow rust package.

Since arrow-rs specifies 1.62 on the Cargo.toml, this may be better discussed in this issue apache/arrow-rs#181.
