## WORK IN PROGRESS

An Entity Component System for Rust. Fast, easy, and predictable.

* No `unsafe`

* No dependencies

```rust

struct Health(f32);

struct Name(String);

struct CreepySnakeHair(u32);

let mut world = World::new();

// Create entities with components.

world.spawn((Name("Perseus".to_string()), Health(50.)));

world.spawn((

    Name("Medusa".to_string()),

    Health(100.),

    CreepySnakeHair(300),

));

// Find every entity with a `Name` and a `Health` component.

let mut query = world.query::<(&Name, &Health)>().unwrap();

// Iterate through all entities with those components.

for (name, health) in query.iter() {

    println!("{}'s health is: {:?}", name.0, health.0);

}

```

`Kudo` was inspired by the library [`hecs`](https://github.com/Ralith/hecs). If you need a more feature-rich ECS, give `hecs` a try!
