//! See [RFC as Readme-For-Crate](https://github.com/oooutlk/structx/blob/main/README.md)
//! for more.
//!
//! # Overview
//!
//! This project provides simulation of anonymous struct and named arguments in
//! Rust, using proc macros `structx!{}`, `Structx!{}`, `#[named_args]` and
//! `args!{}`.
//!
//! ## Usage of this crate
//!
//! Add the following in your Cargo.toml file:
//!
//! ```toml
//! [dependencies]
//! structx = "0.1"
//!
//! [build-dependencies]
//! inwelling = "0.4"
//!
//! [package.metadata.inwelling]
//! structx = true
//! ```
//!
//! Add the following in your build.rs file:
//!
//! ```rust
//! inwelling::to( "structx" );
//! ```
//! Add the following in your .rs files:
//!
//! ```rust,no_run
//! use structx::*;
//! ```
//!
//! If you want to use named arguments, add the following:
//!
//! ```rust,no_run
//! use structx::named_args::*;
//! ```
//!
//! # Definitions and notations of anonymous structs
//!
//! Anonymous structs are `struct`s without the needs of providing struct names.
//! However, the field names are mandatory. Anonymous structs are of the same type
//! if and only if they are composed of the same set of field names. The order of
//! fields are irrelevant.
//!
//! ## Value of anonymous structs
//!
//! The notation of an anonymous struct's value is `structx!{}`.
//!
//! ## Examples of anonymous struct's values
//!
//! ```rust,no_run
//! let foo = structx!{ i: 3, b: true };
//! let bar = structx!{ x, y };
//! ```
//!
//! ## Type of anonymous structs
//!
//! The notation of an anonymous struct's type is `Structx!{}`.
//!
//! ## Examples of anonymous struct's types
//!
//! ```rust,no_run
//! fn foo( x: i32, y: i32 ) -> Structx!{ x: i32, y: i32 } {
//! structx!{ x, y: y+1 }
//! }
//! ```
//! ## Traits derived for anonymous structs
//!
//! Clone, Copy, Debug, Default, PartialEq, Eq, PartialOrd, Ord, Hash.
//!
//! ```rust
//! let a = structx!{ width : 800, height: 600 };
//! let b = structx!{ height: 600, width : 800 };
//! let c = structx!{ width : 1024, height: 768 };
//! assert_eq!( a, b );
//! assert_ne!( a, c );
//! ```
//!
//! # Simulation of named arguments
//!
//! At definition site, add attributes `#[named_args]` to functions.
//!
//! ```rust,no_run
//! #[named_args]
//! fn set_size( width: u32, height: u32 ) { todo!() }
//! ```
//!
//! At call site, wrap arguments with `args!{}`.
//!
//! ```rust,no_run
//! set_size( args!{ width: 1024, height: 768 });
//! ```
