//! A data engine for Data Oriented Design.
//! `crate::v9` is a vastly simpler version of `crate::v11`.
//!
//! # Design
//! A `Universe` has the same shape as a `HashMap<TypeId, Any>`.
//! A single instance of any type can be inserted into the universe.
//! Changes can then be made by `run`ning a `Kernel`.
//! A `Kernel` is any closure whose arguments all implement `Extract`.
//! `Extract` indicates to the `Universe` what resources it needs,
//! and does whatever is necessary to provide itself as an argument to the kernel.
//!
//! This crate intentionally shares more fields that you might expect.
//! It's hard to foresee all needs; hopefully you can do something useful with them.

#[macro_use]
extern crate mopa;

// FIXME: Use UniquePtr, etc...?
// FIXME: Add universe.deny(TypeId) to allow constraints like "table is not sparse"
