These are the steps to install Rust in the user's home folder. After you log in, start up a terminal app. In the terminal window run the following commands:

curl --proto '=https' --tlsv1.3 https://sh.rustup.rs -sSf | sh

Chose the first option to install (default) Then run:

source "$HOME/.cargo/env"
cargo install evcxr_jupyter
evcxr_jupyter --install

After that exit out of the terminal window by typing “exit”. Then reload your Jupyterhub window from the Browser. You should now see the Rust icons in the Jupyter notebook.
