+This crate also supports serialization/deserialization through the

+crate is not supported in the 0.3+ series of the `toml` crate, but 0.2 can be
+used for that support.

-//! A TOML-parsing library
+//! A [TOML]-parsing library
 //!
-//! This library is an implementation in Rust of a parser for TOML configuration
-//! files [1]. It is focused around high quality errors including specific spans
-//! and detailed error messages when things go wrong.
+//! This library implements a [TOML] v0.4.0 compatible parser,
+//! primarily supporting the [`serde`] library for encoding/decoding
+//! various types in Rust.
 //!
-//! This implementation currently passes the language agnostic [test suite][2].
+//! TOML itself is a simple, ergonomic, and readable configuration format:
 //!
-//! # Example
+//! ```toml
+//! [package]
+//! name = "toml"
+//! version = "0.4.2"
+//! authors = ["Alex Crichton <alex@alexcrichton.com>"]
 //!
-//! ```
-//! let toml = r#"
-//!     [test]
-//!     foo = "bar"
-//! "#;
-//!
-//! let value = toml::Parser::new(toml).parse().unwrap();
-//! println!("{:?}", value);
+//! [dependencies]
+//! serde = "1.0"
 //! ```
 //!
-//! # Conversions
+//! The TOML format tends to be relatively common throughout the Rust community
+//! for configuration, notably being used by [Cargo], Rust's package manager.
 //!
-//! This library also supports using the standard `Encodable` and `Decodable`
-//! traits with TOML values. This library provides the following conversion
-//! capabilities:
+//! ## TOML values
 //!
-//! * `String` => `toml::Value` - via `Parser`
-//! * `toml::Value` => `String` - via `Display`
-//! * `toml::Value` => rust object - via `Decoder`
-//! * rust object => `toml::Value` - via `Encoder`
+//! A value in TOML is represented with the `Value` enum in this crate:
 //!
-//! Convenience functions for performing multiple conversions at a time are also
-//! provided.
+//! ```rust,ignore
+//! pub enum Value {
+//!     String(String),
+//!     Integer(i64),
+//!     Float(f64),
+//!     Boolean(bool),
+//!     Datetime(Datetime),
+//!     Array(Array),
+//!     Table(Table),
+//! }
+//! ```
 //!
-//! [1]: https://github.com/mojombo/toml
-//! [2]: https://github.com/BurntSushi/toml-test
+//! TOML is similar to JSON with the notable addition of a `Datetime`
+//! type. In general, TOML and JSON are interchangeable in terms of
+//! formats.
+//!
+//! ## Parsing TOML
+//!
+//! The easiest way to parse a TOML document is via the `Value` type:
+//!
+//! ```rust
+//! use toml::Value;
+//!
+//! let value = "foo = 'bar'".parse::<Value>().unwrap();
+//!
+//! assert_eq!(value["foo"].as_str(), Some("bar"));
+//! ```
+//!
+//! The `Value` type implements a number of convenience methods and
+//! traits; the example above uses `FromStr` to parse a `str` into a
+//! `Value`.
+//!
+//! ## 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 Value`
+//! * `Serialize for Value`
+//! * `Deserialize for Datetime`
+//! * `Serialize for Datetime`
+//! * `Deserializer for de::Deserializer`
+//! * `Serializer for ser::Serializer`
+//! * `Deserializer for Value`
+//!
+//! This means that you can use Serde to deserialize/serialize the
+//! `Value` type as well as the `Datetime` type in this crate. You can also
+//! use the `Deserializer`, `Serializer`, or `Value` type itself to act as
+//! a deserializer/serializer for arbitrary types.
+//!
+//! An example of deserializing with TOML is:
+//!
+//! ```rust
+//! #[macro_use]
+//! extern crate serde_derive;
+//! extern crate toml;
+//!
+//! #[derive(Deserialize)]
+//! struct Config {
+//!     ip: String,
+//!     port: Option<u16>,
+//!     keys: Keys,
+//! }
+//!
+//! #[derive(Deserialize)]
+//! struct Keys {
+//!     github: String,
+//!     travis: Option<String>,
+//! }
+//!
+//! fn main() {
+//!     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:
+//!
+//! ```rust
+//! #[macro_use]
+//! extern crate serde_derive;
+//! extern crate toml;
+//!
+//! #[derive(Serialize)]
+//! struct Config {
+//!     ip: String,
+//!     port: Option<u16>,
+//!     keys: Keys,

+//! Serializing Rust structures into TOML.
+//!
+//! This module contains all the Serde support for serializing Rust structures
+//! into TOML documents (as strings). Note that some top-level functions here
+//! are also provided at the top of the crate.
+//!
+//! Note that the TOML format has a restriction that if a table itself contains
+//! tables, all keys with non-table values must be emitted first. This is
+//! typically easy to ensure happens when you're defining a `struct` as you can
+//! reorder the fields manually, but when working with maps (such as `BTreeMap`
+//! or `HashMap`) this can lead to serialization errors. In those situations you
+//! may use the `tables_last` function in this module like so:
+//!
+//! ```rust
+//! # #[macro_use] extern crate serde_derive;
+//! # extern crate toml;
+//! # use std::collections::HashMap;
+//! #[derive(Serialize)]
+//! struct Manifest {
+//!     package: Package,
+//!     #[serde(serialize_with = "toml::ser::tables_last")]
+//!     dependencies: HashMap<String, Dependency>,
+//! }
+//! # type Package = String;
+//! # type Dependency = String;
+//! # fn main() {}
+//! ```

Subject: [PATCH 13/22] bug 1445183 store TRR duration when the response is
 used r=valentin

Previously it would store the time even for early AAAA responses that
weren't used until the A response came in, thus getting the timing
wrong.
