save_image

Saves the image from the url to the given path. Returns the path on success ``` use reqwest::Client; use std::env; use std::fs::removefile; let client = Client::new(); let workpath = env::currentdir().unwrap().join("1489266570954.jpg"); let url = "https://i.4cdn.org/wg/1489266570954.jpg"; let answer = chandownloader::saveimage(url, workpath.to_str().unwrap(), &client).unwrap();

asserteq!(workpath.tostr().unwrap(), answer); remove_file(answer).unwrap(); ```

getpagecontent

Returns the page content from the given url. use reqwest::Client; let client = Client::new(); let url = "https://boards.4chan.org/wg/thread/6872254"; match chan_downloader::get_page_content(url, &client) { Ok(page) => println!("Content: {}", page), Err(err) => eprintln!("Error: {}", err), }

getthreadinfos

Returns the board name and thread id. let url = "https://boards.4chan.org/wg/thread/6872254"; let (board_name, thread_id) = chan_downloader::get_thread_infos(url); /// assert_eq!(board_name, "wg"); assert_eq!(thread_id, "6872254");

getimagelinks

Returns the links and the number of links from a page. Note that the links are doubled. ``` use reqwest::Client; let client = Client::new(); let url = "https://boards.4chan.org/wg/thread/6872254"; match chandownloader::getpagecontent(url, &client) { Ok(pagestring) => { let (linksiter, numberoflinks) = chandownloader::getimagelinks(pagestring.asstr());

    assert_eq!(number_of_links, 4);

    for cap in links_iter.step_by(2) {
        println!("{} and {}", &cap[1], &cap[2]);
    }
},
Err(err) => eprintln!("Error: {}", err),

} ```
