How to enter command line argument with docops?

Question

How can I enter command line arguments in Rust using docopts? I'd like to simply be able to enter a u8 in a vector and parse it with docopts.

In this case, you should show some example code of what you tried. Or maybe some search results for things you've looked up but don't understand. At the very least, you could write some example code (or pseudocode) that better explains what you want to do. — Shepmaster, Mar 21 '15 at 00:45

You can use the std::env::args method to obtain an iterator. Then, you can use .collect on the iterator to get a vector of Strings.

use std::env;
fn main () {
    let args: Vec<String> = env::args().collect();
    println!("{:?}", args);
}

Example output:

simon@Simon-Desktop:~$ rustc t.rs 
simon@Simon-Desktop:~$ ./t abc def
["./t", "abc", "def"]
