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 "] //! //! [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::().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, //! keys: Keys, //! } //! //! #[derive(Deserialize)] //! struct Keys { //! github: String, //! travis: Option, //! } //! //! 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, //! keys: Keys, //! } //! //! #[derive(Serialize)] //! struct Keys { //! github: String, //! travis: Option, //! } //! //! 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(); //! ``` //! //!
