Crate spider_middleware 

spider-middleware

Built-in middleware for the crawler runtime.

This crate contains the request/response hooks that sit between scheduling, downloading, and parsing. It is the right layer for retry policy, rate limiting, cookies, proxies, user agents, robots.txt, and caching.

Example

use spider_middleware::{rate_limit::RateLimitMiddleware, retry::RetryMiddleware};

let crawler = CrawlerBuilder::new(MySpider)
    .add_middleware(RateLimitMiddleware::default())
    .add_middleware(RetryMiddleware::new())
    .build()
    .await?;
