You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: agent_battle.rs
    path of file: ./repos/rs-poker/examples
    
    the code of the file until where you have to start completion: extern crate rs_poker;

use rs_poker::arena::{
    agent::{RandomAgent, RandomPotControlAgent},
    comp
    
fn main() {
    // Start with very random dumb agents.
    let agents: Vec<Box<dyn CloneAgent>> = vec![
        Box::<RandomAgent>::default(),
        Box::new(RandomPotControlAgent::new(vec![0.7, 0.3])),
        Box::new(RandomPotControlAgent::new(vec![0.5, 0.3])),
        Box::new(RandomPotControlAgent::new(vec![0.3, 0.1])),
        Box::<RandomAgent>::default(),
    ];
    // Run the games with completely random hands.
    // Starting stack of at least 10 big blinds (10x10=100 chips)
    // Starting stack of no more than 1000 big blinds (10x1000=10000 chips)
    // This isn't deep stack poker at it's finest.
