//! # html5_ext
//!
//! This is set of unofficial extensions to the [html5ever](https://github.com/servo/html5ever) crate's RcDom and Node structs, including a ***minifying HTML5 serializer*** and support for ***CSS matching**.
//!
//! It re-exports the `css` and `html5ever` crates, and useful DOM types hidden inside the `::html5ever::markup5ever::rcdom` module.
//!
//!
//! ## How Tos
//!
//!
//! ### To load and minify HTML5
//!
//! ```
//! extern crate html5_ext;
//! use ::html5ever_ext::RcDom;
//! use ::html5ever_ext::RcDomExt;
//! use ::html5ever_ext::Minify;
//!
//! let rc_dom = RcDom::from_file_path_verified_and_stripped_of_comments_and_processing_instructions_and_with_a_sane_doc_type("/path/to/document.html").expect("invalid HTML");
//! rc_dom.minify_to_file_path();
//! ```
//!
//! There are additional methods available on `Minify` to minify to a byte array or a generic `Write`-implementing writer.
//!
//! For more control, eg over serializing multiple node graphs, use the struct `UltraMinifyingHtmlSerializer` directly.
//!
//!
//! ### To match CSS selectors
//!
//! ```
//! extern crate html5_ext;
//! use ::html5ever_ext::RcDom;
//! use ::html5ever_ext::RcDomExt;
//! use ::html5ever_ext::parse_css_selector;
//! use ::html5ever_ext::Selectable;
//! use ::html5ever_ext::Minify;
//!
//! let rc_dom = RcDom::from_file_path_verified_and_stripped_of_comments_and_processing_instructions_and_with_a_sane_doc_type("/path/to/document.html").expect("invalid HTML");
//!
//! let selector = parse_css_selector("p.myclass").unwrap();
//!
//! assert!(!rc_dom.matches(&selector));
//!
//! rc_dom.find_all_matching_child_nodes_depth_first_including_this_one(&selector, |node|
//! {
//! 	eprintln!("{}", node.debug_string());
//!
//! 	const SHORTCUT: bool = false;
//! 	SHORTCUT
//! })
//! ```
//!
//! ### To work with Nodes
//!
//! Use the `NodeExt`, `Minify`, `Selectable` and `QualNameExt` traits.
//!
