[Dhall][dhall] is a programmable configuration language that provides a non-repetitive -//! alternative to JSON and YAML. -//! -//! You can think of Dhall as: JSON + types + imports + functions -//! -//! For a description of the dhall language, examples, tutorials, and more, see the [language -//! website][dhall]. -//! -//! This crate provides support for consuming dhall files the same way you would consume JSON or -//! YAML. It uses the [Serde][serde] serialization library to provide drop-in support for dhall -//! for any datatype that supports serde (and that's a lot of them !). -//! -//! This library is limited to deserializing (reading) dhall values; serializing (writing) -//! values to dhall is not supported for now. -//! -//! # Examples -//! -//! ### Custom datatype -//! -//! If you have a custom datatype for which you derived [serde::Deserialize], chances are -//! you will be able to derive [StaticType][de::StaticType] for it as well. -//! This gives you access to a dhall representation of your datatype that can be outputted -//! to users, and allows easy type-safe deserializing. -//! -//! ```edition2018 -//! use serde::Deserialize; -//! use dhall::de::StaticType; -//! -//! #[derive(Debug, Deserialize, StaticType)] -//! struct Point { -//! x: u64, -//! y: u64, -//! } -//! -//! fn main() { -//! // Some dhall data -//! let data = "{ x = 1, y = 1 + 1 }"; -//! -//! // Convert the dhall string to a Point. -//! let point: Point = -//! dhall::de::from_str_auto_type(&data) -//! .expect("An error ocurred !"); -//! -//! // Prints "point = Point { x: 1, y: 2 }" -//! println!("point = {:?}", point); -//! } -//! ``` -//! -//! ### Loosely typed -//! -//! If you used to consume JSON or YAML in a loosely typed way, you can continue to do so -//! with dhall. You only need to replace [serde_json::from_str] or [serde_yaml::from_str] -//! with [dhall::de::from_str][de::from_str]. -//! More generally, if the [StaticType][de::StaticType] derive doesn't suit your -//! needs, you can still deserialize any valid dhall file that serde can handle. -//! -//!

[serde_yaml::from_str]: https://docs.serde.rs/serde_yaml/fn.from_str.html -//! -//! ```edition2018 -//! use std::collections::BTreeMap; -//! -//! let mut map = BTreeMap::new(); -//! map.insert("x".to_string(), 1); -//! map.insert("y".to_string(), 2); -//! -//! // Some dhall data -//! let data = "{ x = 1, y = 1 + 1 } : { x: Natural, y: Natural }"; -//! -//! // Deserialize it to a Rust type. -//! let deserialized_map: BTreeMap<String, usize> = -//! dhall::de::from_str(&data, None) -//! .expect("Failed reading the data !"); -//! assert_eq!(map, deserialized_map); -//! ``` -//! -//! You can of course specify a dhall type that the input should match. -//! -//! ```edition2018 -//! use std::collections::BTreeMap; -//! -//! let mut map = BTreeMap::new(); -//! map.insert("x".to_string(), 1); -//! map.insert("y".to_string(), 2); -//! -//! // Some dhall data -//! let point_data = "{ x = 1, y = 1 + 1 }"; -//! let point_type_data = "{ x: Natural, y: Natural }"; -//! -//! // Construct a type -//! let point_type = -//! dhall::de::from_str(point_type_data, None) -//! .expect("Could not parse the Point type"); -//! -//! // Deserialize it to a Rust type. -//! let deserialized_map: BTreeMap<String, usize> = -//! dhall::de::from_str(&point_data, Some(&point_type)) -//! .expect("Failed reading the data !"); -//! assert_eq!(map, deserialized_map); -//! ``` -//! -//!
