//! A [serde]-compatible [TOML]-parsing library
//!
//! TOML itself is a simple, ergonomic, and readable configuration format:
//!
//! ```toml
//! [package]
//! name = "toml"
//! version = "0.4.2"
//! authors = ["Alex Crichton <alex@alexcrichton.com>"]
//!
//! [dependencies]
//! serde = "1.0"
//! ```
//!
//! The TOML format tends to be relatively common throughout the Rust community
//! for configuration, notably being used by [Cargo], Rust's package manager.
//!
//! ## TOML values
//!
//! A TOML document is represented with the [`Table`] type which maps `String` to the [`Value`] enum:
//!
//! ```rust
//! # use toml::value::{Datetime, Array, Table};
//! pub enum Value {
//! String(String),
//! Integer(i64),
//! Float(f64),
//! Boolean(bool),
//! Datetime(Datetime),
//! Array(Array),
//! Table(Table),
//! }
//! ```
//!
//! ## Parsing TOML
//!
//! The easiest way to parse a TOML document is via the [`Table`] type:
//!
//! use toml::Table;
//!
//! let value = "foo = 'bar'".parse::<Table>().unwrap();
//!
//! assert_eq!(value["foo"].as_str(), Some("bar"));
//! ```
//!
//! The [`Table`] type implements a number of convenience methods and
//! traits; the example above uses [`FromStr`] to parse a [`str`] into a
//! [`Table`].
//!
//! ## Deserialization and Serialization
//!
//! This crate supports [`serde`] 1.0 with a number of
//! implementations of the `Deserialize`, `Serialize`, `Deserializer`, and
//! `Serializer` traits. Namely, you'll find:
//!
//! * `Deserialize for Table`
//! * `Serialize for Table`
//! * `Deserialize for Value`
//! * `Serialize for Value`
//! * `Deserialize for Datetime`
//! * `Serialize for Datetime`
//! * `Deserializer for de::Deserializer`
//! * `Serializer for ser::Serializer`
//! * `Deserializer for Table`
//! * `Deserializer for Value`
//!
//! This means that you can use Serde to deserialize/serialize the
//! [`Table`] type as well as [`Value`] and [`Datetime`] type in this crate. You can also
//! use the [`Deserializer`], [`Serializer`], or [`Table`] type itself to act as
//! a deserializer/serializer for arbitrary types.
//!
//! An example of deserializing with TOML is:
//!
//! use serde::Deserialize;
//!
//! #[derive(Deserialize)]
//! struct Config {
//! ip: String,
//! port: Option<u16>,
//! keys: Keys,
//! }
//!
//! #[derive(Deserialize)]
//! struct Keys {
//! github: String,
//! travis: Option<String>,
//! }
//!
//! let config: Config = toml::from_str(r#"
//! ip = '127.0.0.1'
//!
//! [keys]
//! github = 'xxxxxxxxxxxxxxxxx'
//! travis = 'yyyyyyyyyyyyyyyyy'
//! "#).unwrap();
//!
//! assert_eq!(config.ip, "127.0.0.1");
//! assert_eq!(config.port, None);
//! assert_eq!(config.keys.github, "xxxxxxxxxxxxxxxxx");
//! assert_eq!(config.keys.travis.as_ref().unwrap(), "yyyyyyyyyyyyyyyyy");
//! ```
//!
//! You can serialize types in a similar fashion:
//!
//! use serde::Serialize;
//!
//! #[derive(Serialize)]
//! struct Config {
//! ip: String,
//! port: Option<u16>,
//! keys: Keys,
//! }
//!
//! #[derive(Serialize)]
//! struct Keys {
//! github: String,
//! travis: Option<String>,
//! }
//!
//! let config = Config {
//! ip: "127.0.0.1".to_string(),
//! port: None,
//! keys: Keys {
//! github: "xxxxxxxxxxxxxxxxx".to_string(),
//! travis: Some("yyyyyyyyyyyyyyyyy".to_string()),
//! },
//! };
//!
//! let toml = toml::to_string(&config).unwrap();
//! ```
