//! Array concatenation
//!
//! This crate allows concatenating multiple arrays of varying lengths into one array.
//!
//! # Example
//!
//! ### `concat_arrays`
//!
//! For more examples of using [`concat_arrays`],
//! you can [look here][concat_arrays_examples].
//!
//! ```rust
//! use arrcat::concat_arrays;
//!
//! {
//!     const PRIMES: [u16; 4] = [7, 11, 13, 17];
//!     assert_eq!(
//!         concat_arrays!([3, 4, 4u16.pow(3)], PRIMES),
//!         [3, 4, 64, 7, 11, 13, 17],
//!     );
//! }
//!
//! {
//!
//!     let increasing = [8, 9, 10];
//!
//!     let concated = concat_arrays!(
//!         // the macro can't infer the length of runtime array non-literals.
//!         increasing: [_; 3],
//!         // most non-literal arguments need to be wrapped in `()` or `{}`.
//!         ([2u16, 3, 4].map(|x| x * 9)): [_; 3],
//!     );
//!
//!     assert_eq!(concated, [8, 9, 10, 18, 27, 36]);
//! }
//!
//! ```
//!
//! # No-std support
//!
//! `arrcat` is `#![no_std]`, it can be used anywhere Rust can be used.
//!
//! # Minimum Supported Rust Version
//!
//! `arrcat` requires Rust 1.57.0, requiring crate features to use newer language features.
//!
//!
//! [concat_arrays_examples]: crate::concat_arrays#examples
