## 爬虫程序设计

Why use Rust?

1. Async I/O Model, best performance possible when making requests.

2. Memory-related performance.

3. Safety when parsing.

4. Associated types.

5. 并发支持

6. 学习构建 rust project

业务架构示意图

- Crawler 爬虫：负责对访问的 url 列表进行管理，获取网页响应；

	- Control loop：queue urls

1）构建一个 CrawlerConfig 来对 Crawler 进行参数配置和初始化

	- 默认值和便捷方法

	- allow or disallow domain

	- concurrent_requests

2）需要构建一个 Crawler 结构体来实现主体功能

依赖库：

- 网络请求库：reqwest
