rustup - The Rust toolchain installer

If you want to use the versions of rust installed through rustup by default
for everything, you'll need to add links to the rustup binary on your path
before the system rust.

You are free to choose where, but here is an example for a single user:

mkdir -p $HOME/.rustup/shims
for lnk in cargo cargo-fmt rls rustc rustdoc rustfmt rust-gdb rust-lldb ; do
  (
    cd $HOME/.rustup/shims
    ln -s /usr/bin/rustup $lnk
  )
done

Then add the directory to your path (.bashrc for example):
export PATH="$HOME/.rustup/shims:$PATH"
