//! # Chapter 0: Introduction
//!
//! This tutorial assumes that you are:
//! - Already familiar with Rust
//! - Using `winnow` for the first time
//!
//! The focus will be on parsing in-memory strings (`&str`). Once done, you might want to check the
//! [Special Topics][_topic] for more specialized topics or examples.
//!
//! ## About
//!
//! `winnow` is a parser-combinator library. In other words, it gives you tools to define:
//! - "parsers", or functions that take an input and give back an output
//! - "combinators", or functions that take parsers and _combine_ them together!
//!
//! While "combinator" might be an unfamiliar word, you are likely using them in your rust code
//! today, like with the [`Iterator`] trait:
//! ```rust
//! let data = vec![1, 2, 3, 4, 5];
//! let even_count = data.iter()
//!     .copied()  // combinator
//!     .filter(|d| d % 2 == 0)  // combinator
//!     .count();  // combinator
//! ```
//!
//! Parser combinators are great because:
//!
//! - Individual parser functions are small, focused on one thing, ignoring the rest
//! - You can write tests focused on individual parsers (unit tests and property-based tests)
//!   in addition to testing the top-level parser as a whole.
//! - Top-level parsing code looks close to the grammar you would have written
