Entity Component

The entity-component part of a full ECS (Entity-Component-System).

Usage

Add the following to you Cargo.toml file: entity_component = "0.99.0"

Use it like so: ```rust use entity_component::*;

fn main() { // Creating components struct A(f32); struct B(f32); // Creating entity repository let mut entities = Entities::default(); // Creating component storages let mut storage = Components::::default(); let mut storage2 = Components::::default(); // Create entities and add components for i in 0..10000 { let e = entities.create(); if i % 5 == 0 { storage.insert(e, A(1.0)); } if i % 6 == 0 { storage2.insert(e, B(1.0)); } } // Join on all entities having both A and B. // We take a mutable reference to the A component and an immutable // reference to the B component. join!(&mut storage && &storage2) .for_each(|(s, s2)| s.unwrap().0 += s2.unwrap().0);

// Same thing, but we also get the entities id that align with the
// matched components.
join!(&entities && &mut storage && &storage2)
    .for_each(|(_e, s, s2)| s.unwrap().0 += s2.unwrap().0);
