//! Pull parser for [CommonMark](https://commonmark.org). This crate provides a [Parser](struct.Parser.html) struct
//! which is an iterator over [Event](enum.Event.html)s. This iterator can be used
//! directly, or to output HTML using the [HTML module](html/index.html).
//!
//! By default, only CommonMark features are enabled. To use extensions like tables,
//! footnotes or task lists, enable them by setting the corresponding flags in the
//! [Options](struct.Options.html) struct.
//!
//! # Example
//! ```rust
//! use pulldown_cmark::{Parser, Options, html};
//!
//! let markdown_input = "Hello world, this is a ~~complicated~~ *very simple* example.";
//!
//! // Set up options and parser. Strikethroughs are not part of the CommonMark standard
//! // and we therefore must enable it explicitly.
//! let mut options = Options::empty();
//! options.insert(Options::ENABLE_STRIKETHROUGH);
//! let parser = Parser::new_ext(markdown_input, options);
//!
//! // Write to String buffer.
//! let mut html_output = String::new();
//! html::push_html(&mut html_output, parser);
//!
//! // Check that the output is what we expected.
//! let expected_html = "<p>Hello world, this is a <del>complicated</del> <em>very simple</em> example.</p>\n";
//! assert_eq!(expected_html, &html_output);
//! ```

// When compiled for the rustc compiler itself we want to make sure that this is
// an unstable crate.
