toml 0.5.3

//! A [TOML]-parsing library
//!
//! This library implements a [TOML] v0.5.0 compatible parser,
//! primarily supporting the [`serde`] library for encoding/decoding
//! various types in Rust.
//!
//! 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 value in TOML is represented with the `Value` enum in this crate:
//!
//! ```rust,ignore
//! pub enum Value {
//!     String(String),
//!     Integer(i64),
//!     Float(f64),
//!     Boolean(bool),
//!     Datetime(Datetime),
//!     Array(Array),
//!     Table(Table),
//! }
//! ```
//!
//! 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
//! use serde_derive::Deserialize;
//!
//! #[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
//! use serde_derive::Serialize;
//!
//! #[derive(Serialize)]
//! struct Config {
//!     ip: String,
//!     port: Option<u16>,
//!     keys: Keys,
//! }
//!
//! #[derive(Serialize)]
//! struct Keys {
//!     github: String,
//!     travis: Option<String>,
//! }
//!
//! fn main() {
//!     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();
//! }
//! ```
