//! The definitive vector and matrix library for Rust
//!
//! # In short
//! ![XKCD](https://imgs.xkcd.com/comics/standards.png)
//!
//! My take on a vector library, that tries to be the be-all end-all vector and
//! matrix crate through hand written SIMD for games and const generics for
//! scientific compute.
//!
//! In order to achieve this, `definitive` relies on experimental Rust features,
//! such as const generics and specialization. This puts `definitive` in the
//! experimental category, as it may cause internal compiler errors or undefined
//! behaviour.
//!
//! # Matrices?
//! You might ponder, for a vector and **matrix** library, `definitive` doesn't
//! seem to have any matrices! This is an unfortunate issue that I am currently
//! facing with const generics that should be resolved in the future. Before
//! support in rustc matures, `definitive` will support "good enough" matrices
//! that aren't const sized.
//!
//! # Example
//! ```rust
//! use definitive::Vector;
//!
//! let a = Vector::from([2, 3, 1]);
//! let b = Vector::from([8, 0, 0]);
//!
//! dbg!(a + b * 4);
//! // [34, 3, 1]
//! ```
//!
//! ### `#![no_std]` is supported by disabling the `std` feature

#![feature(const_generics, specialization, trivial_bounds)]
#![allow(incomplete_features)]
#![deny(missing_docs)]
#![cfg_attr(not(feature = "std"), no_std)]
