Rust Setup

I prefer using home-brew to manage the install package. So I'm used to searching first.

Home-brew

brew info rustup-init

DISCUSSION:
    Rustup installs The Rust Programming Language from the official
    release channels, enabling you to easily switch between stable,
    beta, and nightly compilers and keep them updated. It makes
    cross-compiling simpler with binary builds of the standard library
    for common platforms.

    If you are new to Rust consider running `rustup doc --book` to
    learn Rust.
