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: queue.rs
    path of file: ./repos/phaser/phaser/vendor/tokio/src/runtime/tests
    
    the code of the file until where you have to start completion: use crate::runtime::queue;
use crate::runtime::stats::WorkerStatsBatcher;
use crate::runtime::task::{self, Inject, Schedule, Task};

use std::thread;
use std::time::Duration;

#[test]
fn fits_256() {
    let (_, mut local) = queue::local();
    let inject = Inject::new();

    for _ in 0..256 {
        let (task, _) = super::unowned(async {});
        local.push_back(task, &inject);
    }

    assert!(inject.pop().is_none());

    while local.pop().is_some() {}
}

#[test]
fn overflow() {
    let (_, mut local) = queue::local();
    let i
    
fn steal_batch() {
    let mut stats = WorkerStatsBatcher::new(0);

    let (steal1, mut local1) = queue::local();
    let (_, mut local2) = queue::local();
    let inject = Inject::new();

    for _ in 0..4 {
        let (task, _) = super::unowned(async {});
        local1.push_back(task, &inject);
    }

    assert!(steal1.steal_into(&mut local2, &mut stats).is_some());

    for _ in 0..1 {
        assert!(local2.pop().is_some());
    }

    assert!(local2.pop().is_none());

    for _ in 0..2 {
        assert!(local1.pop().is_some());
    }

    assert!(local1.pop().is_none());
}
