Welcome to Rust.
This script will download the Rust compiler and its package manager, Cargo, and
install them to /usr/local. You may install elsewhere by running this script
with the --prefix=<path> option.
The installer will run under ‘sudo‘ and may ask you for your password. If you do
not want the script to run ‘sudo‘ then pass it the --disable-sudo flag.
You may uninstall later by running /usr/local/lib/rustlib/uninstall.sh,
or by running this script again with the --uninstall flag.
Continue? (y/N) y
