miniqueue

一个极简的通用多线程队列，它聚合结果并将更多任务填充到队列中。

其语义与fold/reduce相反：它不是从一个数据集开始，而是从一个数据点开始，递归遍历它以展开更大的结构。

当处理依赖图时非常有用。它可用于编译器、包管理器和链接器/打包器。

用法

以下是一个简单的示例

let all_results = miniqueue::run(first_job, |job| {
    let (result, more_jobs) = run_job(job)
    (result, more_jobs)
});

将第一个应该运行的作业作为第一个参数传递。

第二个参数是一个闭包，它接收一个作业并执行它，并且应该返回一个包含

• 的元组<强>作业结果
• 一个包含更多需要在下一次迭代中执行的<强>作业

的所有作业都将被入队以供稍后执行。注意，以前已经执行过的作业将不会被再次调度。

<强>run的最终结果是一个HashMap，它聚合了<强>作业和<强>作业结果。

<强>作业和<强>作业结果都是泛型类型，因此可以是任何你想要的东西。

以下是一个包含自包含示例的测试用例

use miniqueue;

let result = run(1, |num| {
    match num {
        1 => Ok(("one", vec![ 2 ])),
        2 => Ok(("two", vec![])),
        _ => Ok(("", vec![]))
    }
});

assert_eq!(result.unwrap().get(&1), Some(&"one"));
