An Entity Component System (ECS) library written in Rust.
For info about why an ECS may be beneficial, see some of these articles:
There is a large variety of ways an ECS may work. This particular one is similar to Artemis. Although this isn't a port to Rust, most functionality should be similar, and the tutorials/manual there should be able to make up for the current lack of documentation here.
A little more information is available in the rustdocs.
Run:
$ cargo doc
With ecs-rs as one of the dependencies, and open the ecs
docs up in your browser of choice.
