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 mapping 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.
