Rust

Rust is a general-purpose programming language emphasizing performance, type safety, concurrency and enforces memory safety.

Cargo

Cargo is the Rust package manager. Cargo downloads your Rust package's dependencies, compiles your packages, makes distributable packages, etc.

Starting with Debian bookworm, we opt for a central installation of the rustc compiler and cargo package manager, which we will keep up to date with the default stable rust toolchain.

Upon login on a managed Linux workstation, your environment variables will be setup automatically to include the rust toolchain binaries located in /opt/software/rust in your PATH variable.

You can inspect the relevant environment variables using:

env | grep -E 'PATH|CARGO|RUST'

Build or install

Just run cargo build or cargo install <foo>, which will use your local ~/.cargo directory as target.

For research projects, group projects or due to disk space quota limits on home directories, please redirect larger rust projects onto some other storage medium, such as /scratch. You can do so using the CARGO_HOME environment variable, example:

export CARGO_HOME="/scratch/${USER}/.cargo"

Clean cache

Please regularly clean your cache in ~/.cargo using:

cargo cache -i           # print infos about cache directories
cargo cache -a           # autoclean cache directories
rm -r ~/.cargo/registry  # clean registry cache

Manual environment setup

To set up /opt/software/rust manually:

export RUSTUP_HOME=/opt/software/rust/rustup
export PATH="${PATH:+${PATH}:}/opt/software/rust/cargo/bin"
export PATH="${PATH:+${PATH}:}${HOME}/.cargo/bin"

Versions and software

You find older versions using: ls -la /opt/software/rust. If your required version is not available, please contact us.

We also have the option to centrally pre-install other frequently used software or rust crates.

Rustup

Preferably, please use our central installation as described above, but you may also install any rust or cargo version as user using rustup:

export RUSTUP_HOME="/scratch/${USER}/.rustup"
export CARGO_HOME="/scratch/${USER}/.cargo"
export RUSTUP_INIT_SKIP_PATH_CHECK=yes
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --no-modify-path --quiet -y
. "/scratch/${USER}/.cargo/env"
cargo --version
rustc --version
