Upgrade rust build environment to 1.79

[nkaz001]

What's the problem this feature will solve?

Error

Config validation error in build.tools.rust. Expected one of (1.55, 1.61, 1.64, 1.70, 1.75, 1.78, latest), got type str (1.79). Double check the type of the value. A string may be required (e.g. "3.10" instead of 3.10)

Describe the solution you'd like

Please add Rust 1.79

Additional context

Since my library is using the features which is stabilized in 1.79, downgrading to 1.78 is not an option.

Hi @nkaz001

From our documentation at https://docs.readthedocs.io/en/stable/config-file/v2.html#build-tools

Versions and the latest option are updated at least once every six months to keep up with the latest releases.

We updated the latest versions in June #11386; so we don't plan to update them again until by the end of 2024, probably. Unfortunately, Rust 1.79 was release some days immediately after we update the versions.

That's unfortunate. Is there a way to work around this, such as using the nightly version of 1.78?

You should be able to remove your build.tools.rust entry and then run the commands manually:

asdf install rust 1.79.0
asdf global rust 1.79.0

Let me know if that works.

It works by manually running the build command using build.command. Thank you for your help.
