+//! Deserializing TOML into Rust structures.
+//!
+//! This module contains all the Serde support for deserializing TOML documents
+//! into Rust structures. Note that some top-level functions here are also
+//! provided at the top of the crate.

+/// Deserializes a string into a type.
+///
+/// This function will attempt to interpret `s` as a TOML document and
+/// deserialize `T` from the document.
+///
+/// To deserializes TOML values, instead of documents, see [`ValueDeserializer`].
+///
+/// # Examples
+///
+/// ```
+/// use serde::Deserialize;
+///
+/// #[derive(Deserialize)]
+/// struct Config {
+/// title: String,
+/// owner: Owner,
+/// }
+///
+/// #[derive(Deserialize)]
+/// struct Owner {
+/// name: String,
+/// }
+///
+/// let config: Config = toml::from_str(r#"
+/// title = 'TOML Example'
+///

+//! 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:
+//!
+#![cfg_attr(not(feature = "parse"), doc = " ```ignore")]
+#![cfg_attr(feature = "parse", doc = " ```")]
+//! 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:
+//!
+#![cfg_attr(not(feature = "parse"), doc = " ```ignore")]
+#![cfg_attr(feature = "parse", doc = " ```")]
+//! 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:
+//!
+#![cfg_attr(not(feature = "display"), doc = " ```ignore")]
+#![cfg_attr(feature = "display", doc = " ```")]
+//! 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();
+//! ```

+//! Serializing Rust structures into TOML.

+/// To serialize TOML values, instead of documents, see [`ValueSerializer`].

+/// #[derive(Serialize)]
+/// struct Config {
+/// database: Database,

+/// Serialization for TOML [values][crate::Value].
+///
+/// This structure implements serialization support for TOML to serialize an
+/// arbitrary type to TOML. Note that the TOML format does not support all
+/// datatypes in Rust, such as enums, tuples, and tuple structs. These types
+/// will generate an error when serialized.
+///
+/// Currently a serializer always writes its output to an in-memory `String`,
+/// which is passed in when creating the serializer itself.
+///
+/// # Examples
+///
+/// ```
+/// use serde::Serialize;
+///
+/// #[derive(Serialize)]
+/// struct Config {
+/// database: Database,
+/// }
+///
+/// #[derive(Serialize)]
+/// struct Database {
+/// ip: String,
+/// port: Vec<u16>,
+/// connection_max: u32,
+/// enabled: bool,
+/// }
+///
+/// let config = Config {
+/// database: Database {
+/// ip: "192.168.1.1".to_string(),
+/// port: vec![8001, 8002, 8003],
+/// connection_max: 5000,
+/// enabled: false,
+/// },
+/// };
+///
+/// let mut value = String::new();
+/// serde::Serialize::serialize(
