clippy::ptr_arg

-//! [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_json::from_str]: https://docs.serde.rs/serde_json/de/fn.from_str.html
-//! [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);
