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: main.rs
    path of file: ./repos/perseus/examples/core/plugins/tests
    
    the code of the file until where you have to start completion: use fantoccini::{Client, Locator};
use perseus::wait_for_checkpoint;

// Most of this has already been tested under `ba
    
async fn main(c: &mut Client) -> Result<(), fantoccini::error::CmdError> {
    c.goto("http://localhost:8080").await?;
    wait_for_checkpoint!("begin", 0, c);
    let url = c.current_url().await?;
    assert!(url.as_ref().starts_with("http://localhost:8080"));

    wait_for_checkpoint!("page_interactive", 0, c);
    let greeting = c.find(Locator::Css("p")).await?.text().await?;
    assert_eq!(greeting, "Hello World!");
    // For some reason, retrieving the inner HTML or text of a `<title>` doesn't
    // work
    let title = c.find(Locator::Css("title")).await?.html(false).await?;
    assert!(title.contains("Index Page"));

    // BUG Right now, this is downloaded by the browser...
    // // Check that the static alias to `Cargo.toml` worked (added by a plugin)
    // c.goto("http://localhost:8080/Cargo.toml").await?;
    // let text = c.find(Locator::Css("body")).await?.text().await?;
    // assert!(text.starts_with("[package]"));

    Ok(())
