A little bit of handholding to get Rust going.

README.md

This script downloads the latest nightly and installs (or uninstalls) it as needed.

The steps are:

• Download an extract Rust into a temporary directory.
• Run the install.sh script with the options provided. (Like --uninstall)
• Output necessary config options for the user.

To use:

• Put the script code into any file. (Easiest way is curl $URL_FROM_RAW_BUTTON_OF_SCRIPT > rustup.sh)
• chmod +x rustup.sh
• ./rustup.sh to install.

rustup.sh

#!/bin/bash
# The URL of the Rust nightlies.
URL="http://static.rust-lang.org/dist/rust-nightly-x86_64-unknown-linux-gnu.tar.gz"
# The option that needs to be added to .bashrc or .zshrc
RC_OPTION='export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib"'

function finish {
	rm -rf $DIR
}
trap finish EXIT
