title: How can I access command line parameters in Rust?
body: <p>The <a href="https://doc.rust-lang.org/book/guessing-game.html" rel="noreferrer">Rust tutorial</a> does not explain how to take parameters from the command line. <code>fn main()</code> is only shown with an empty parameter list in all examples.</p>
  <p>What is the correct way of accessing command line parameters from <code>main</code>?</p>
