//! # `gix_config`
//!
//! This crate is a high performance `git-config` file reader and writer. It
//! exposes a high level API to parse, read, and write [`git-config` files].
//!
//! This crate has a few primary offerings and various accessory functions. The
//! table below gives a brief explanation of all offerings, loosely in order
//! from the highest to lowest abstraction.
//!
//! | Offering      | Description                                         | Zero-copy?        |
//! | ------------- | --------------------------------------------------- | ----------------- |
//! | [`File`] | Accelerated wrapper for reading and writing values. | On some reads[^1] |
//! | [`parse::State`]    | Syntactic events for `git-config` files.     | Yes               |
//! | value wrappers | Wrappers for `git-config` value types.            | Yes               |
//!
//! This crate also exposes efficient value normalization which unescapes
//! characters and removes quotes through the `normalize_*` family of functions,
//! located in the [`value`] module.
//!
//! # Examples
//!
//! ## Read And Update Values
//!
//! ```
//! use bstr::ByteSlice;
//! use std::str::FromStr;
//!
//! const SAMPLE: &str = "[core]\neditor = vim\nbare = false\n[remote \"origin\"]\nurl = https://example.com/gitoxide.git\n";
//! let mut config = gix_config::File::from_str(SAMPLE).unwrap();
//! assert_eq!(config.string_by("core", None, "editor").unwrap().as_ref(), "vim");
//! assert_eq!(config.boolean_by("core", None, "bare").unwrap().unwrap(), false);
//!
//! let previous = config.set_raw_value(&"core.editor", "nvim").unwrap().unwrap();
//! assert_eq!(previous.as_ref(), "vim");
//! assert_eq!(config.raw_value("core.editor").unwrap().as_ref(), "nvim");
//! assert!(config.to_bstring().find(b"nvim").is_some());
//! ```
//!
//! # Known differences to the `git config` specification
//!
//! - Legacy headers like `[section.subsection]` are supposed to be turned into to lower case and compared
//!   case-sensitively. We keep its case and compare case-insensitively.
//!
//! [^1]: When read values do not need normalization and it wasn't parsed in 'owned' mode.
