//! > winnow, making parsing a breeze
//!
//! `winnow` is a parser combinator library
//!
//! Quick links:
//! - [List of combinators][crate::combinator]
//! - [Tutorial][_tutorial::chapter_0]
//! - [Special Topics][_topic]
//! - [Discussions](https://github.com/winnow-rs/winnow/discussions)
//! - [CHANGELOG](https://github.com/winnow-rs/winnow/blob/v0.6.24/CHANGELOG.md) (includes major version migration
//!   guides)
//!
//! ## Aspirations
//!
//! `winnow` aims to be your "do everything" parser, much like people treat regular expressions.
//!
//! In roughly priority order:
//! 1. Support writing parser declaratively while not getting in the way of imperative-style
//!    parsing when needed, working as an open-ended toolbox rather than a close-ended framework.
//! 2. Flexible enough to be used for any application, including parsing binary data, strings, or
//!    separate lexing and parsing phases
//! 3. Zero-cost abstractions, making it easy to write high performance parsers
//! 4. Easy to use, making it trivial for one-off uses
//!
//! In addition:
//! - Resilient maintainership, including
//!   - Willing to break compatibility rather than batching up breaking changes in large releases
//!   - Leverage feature flags to keep one active branch
//! - We will support the last 6 months of rust releases (MSRV, currently 1.64.0)
//!
//! See also [Special Topic: Why winnow?][crate::_topic::why]
//!
//! ## Example
//!
//! Run
//! ```console
//! $ cargo add winnow
//! ```
//!
//! Then use it to parse:
//! ```rust
//! # #[cfg(feature = "alloc")] {
#![doc = include_str!("../examples/css/parser.rs")]
//! # }
//! ```
//!
