headless_chrome 1.0.21

Control Chrome programmatically
Documentation
//! A high-level API to control headless Chrome or Chromium over the DevTools Protocol. It is the
//! Rust equivalent of [Puppeteer](https://github.com/GoogleChrome/puppeteer), a Node library
//! maintained by the Chrome DevTools team.
//!
//! It is not 100% feature compatible with Puppeteer, but there's enough here to satisfy most
//! browser testing / web crawling use cases, and there are several 'advanced' features such as:
//!
//! - [network request interception](https://docs.rs/headless_chrome/latest/headless_chrome/browser/tab/struct.Tab.html#method.enable_request_interception)
//! - [JavaScript coverage monitoring](https://docs.rs/headless_chrome/latest/headless_chrome/browser/tab/struct.Tab.html#method.take_precise_js_coverage)
//! - [taking screenshots of elements or the entire page](https://docs.rs/headless_chrome/latest/headless_chrome/browser/tab/struct.Tab.html#method.capture_screenshot)
//! - [saving pages to PDF](https://docs.rs/headless_chrome/latest/headless_chrome/browser/tab/struct.Tab.html#method.print_to_pdf)
//! - ['headful' browsing](https://docs.rs/headless_chrome/latest/headless_chrome/struct.LaunchOptionsBuilder.html#method.headless)
//! - automatic downloading of 'known good' Chromium binaries for Linux / Mac / Windows
//! - [extension pre-loading](https://docs.rs/headless_chrome/latest/headless_chrome/struct.LaunchOptionsBuilder.html#method.extensions)
//!
//! # Quick Start
//!
//! ```no_run
//!use std::error::Error;
//!use headless_chrome::Browser;
//!use headless_chrome::protocol::cdp::Page;
//!
//!fn browse_wikipedia() -> Result<(), Box<dyn Error>> {
//!    let browser = Browser::default()?;
//!
//!    let tab = browser.new_tab()?;
//!
//!    // Navigate to wikipedia
//!    tab.navigate_to("https://www.wikipedia.org")?;
//!
//!    // Wait for network/javascript/dom to make the search-box available
//!    // and click it.
//!    tab.wait_for_element("input#searchInput")?.click()?;
//!
//!    // Type in a query and press `Enter`
//!    tab.type_str("WebKit")?.press_key("Enter")?;
//!
//!    // We should end up on the WebKit-page once navigated
//!    let elem = tab.wait_for_element("#firstHeading")?;
//!    assert!(tab.get_url().ends_with("WebKit"));
//!
//!    /// Take a screenshot of the entire browser window
//!    let jpeg_data = tab.capture_screenshot(
//!        Page::CaptureScreenshotFormatOption::Jpeg,
//!        None,
//!        None,
//!        true)?;
//!    // Save the screenshot to disc
//!    std::fs::write("screenshot.jpeg", jpeg_data)?;
//!
//!    /// Take a screenshot of just the WebKit-Infobox
//!    let png_data = tab
//!        .wait_for_element("#mw-content-text > div > table.infobox.vevent")?
//!        .capture_screenshot(Page::CaptureScreenshotFormatOption::Png)?;
//!    // Save the screenshot to disc
//!    std::fs::write("screenshot.png", png_data)?;
//!
//!    // Run JavaScript in the page
//!    let remote_object = elem.call_js_fn(r#"
//!        function getIdTwice () {
//!            // `this` is always the element that you called `call_js_fn` on
//!            const id = this.id;
//!            return id + id;
//!        }
//!    "#, vec![], false)?;
//!    match remote_object.value {
//!        Some(returned_string) => {
//!            dbg!(&returned_string);
//!            assert_eq!(returned_string, "firstHeadingfirstHeading".to_string());
//!        }
//!        _ => unreachable!()
//!    };
//!
//!    Ok(())
//!}
