Allow building/local running of numtracker on Diamond Workstations

[RJCD-Diamond]

I know this is not the fault Numtracker, and more to do with outdated version of rust in our modules, but I think it should be here.

When trying to follow the README, attempting to run cargo build results in the following error:

error: failed to parse lock file at: /dls/science/users/akz63626/projects/numtracker/Cargo.lock

Caused by:
  lock file version `4` was found, but this version of Cargo does not understand this lock file, perhaps Cargo needs to be updated?

Create a new rust module that is new enough to follow the README instructions on a workstation. Or create a module so that the CLI client can be used on workstations

Do you know what version of rust is available?

[RJCD-Diamond]

rust/1.65.0

[tpoliaw]

Publishing a version as a module is doable but keeping it up to date would be a manual job as I'm not sure how feasible it is to update modules from github actions.

Updating the rust module might be worth doing anyway, 1.65 is three years old now.

Unless you want to sort out the module version, a workaround would be to install a newer version of the toolchain locally (via rustup.rs)

[RJCD-Diamond]

Rust should be updated, and we should raise a ticket with scicomp possible, but ultimately not being able to edit the config for b21 is a blocker for me at the moment, and really that's all I'm trying to do for now. So if installing a newer version via toolchain works then that's fine for me. Although long-term I won't be the only one hitting this issue.

Can you provide instructions?

Can you provide instructions?

Probably not better than the instructions on the rustup site. I'd recommend linking ~/.cargo to a directory on /scratch to avoid home directory quotas, but then it's just a case of running the command from rustup and answering the questions.

Thinking about it, you can also use the container version which means you shouldn't need to build anything.

Alias numtracker to podman run ghcr.io/diamondlightsource/numtracker and then everything on the wiki page should apply (other than the config file which would need the home directory mounting somewhere).
