The shell script rustup.sh is a great way to install Rust and has been used by many developers to not only install Rust, but also Cargo on their machines.

The working of this script is pretty straightforward, where the code of the bash script hosted on the rustup server is downloaded on the host system and run automatically by passing the script code to the pipe symbol. The script offers you various installation options through which you can choose the version and type of Rust compiler you want to install. We have the nightly version, which is not the stable one, in Rust's nightly version. This version is used by developers and contributors to test and develop features for their existing projects.
