At the moment, testing the rust devfile from getting started section in the dashboard: we can build and run ... but no code completion ... nor debug
Could https://github.com/rust-lang/rls-vscode/releases be tested and integrated?

Also it would be nice to see if we could enable the debug mode.

I reinstalled a k3s cluster built with --no-extras and added `--k3s-extra-args="--flannel-backend=host-gw". The cluster failed to start.

I logged in and saw that the output of ps showed the following:

14760 ?        Ssl    0:40 /usr/local/bin/k3s server --cluster-init --tls-san 10.68.0.63 --flannel-backend=host-gw--n

I hope the official can add a new command to automatically generate RESTful API
