lib.rs

//! The `spider-client` module provides the primary interface and
//! functionalities for the Spider web crawler library, which is
//! designed for rapid and efficient crawling of web pages to gather
//! links using isolated contexts.
//!
//! ### Features
//!
//! - **Multi-threaded Crawling:** Spider can utilize multiple
//!   threads to parallelize the crawling process, drastically
//!   improving performance and allowing the ability to gather
//!   millions of pages in a short time.
//!
//! - **Configurable:** The library provides various options to
//!   configure the crawling behavior, such as setting the depth
//!   of crawling, user-agent strings, delays between requests,
//!   and more.
//!
//! - **Link Gathering:** One of the primary objectives of Spider is to
//!   gather and manage links from the web pages it crawls,
//!   compiling them into a structured format for further use.
//!
//! ### Examples
//!
//! Basic usage of the Spider client might look like this:
//!
//! ```rust
//! use spider_client::{Spider, RequestType, RequestParams};
//! use tokio;
//!
//!  # #[ignore]
//! #[tokio::main]
//! async fn main() {
//!     let spider = Spider::new(Some("myspiderapikey".into())).expect("API key must be provided");
//!
//!     let url = "https://spider.cloud";
//!
//!     // Scrape a single URL
//!     let scraped_data = spider.scrape_url(url, None, "application/json").await.expect("Failed to scrape the URL");
//!
//!     println!("Scraped Data: {:?}", scraped_data);
//!
//!     // Crawl a website
//!     let crawler_params = RequestParams {
//!         limit: Some(1),
//!         proxy_enabled: Some(true),
//!         store_data: Some(false),
//!         metadata: Some(false),
//!         request: Some(RequestType::Http),
//!         ..Default::default()
//!     };
//!
//!     let crawl_result = spider.crawl_url(url, Some(crawler_params), false, "application/json", None::<fn(serde_json::Value)>).await.expect("Failed to crawl the URL");
//!
//!     println!("Crawl Result: {:?}", crawl_result);
//! }
//! ```
//!
//! ### Modules
//!
//! - `config`: Contains the configuration options for the Spider client.
//! - `utils`: Utility functions used by the Spider client.
//!
