shred - Shared resource dispatcher

This library allows to dispatch systems, which can have interdependencies, shared and exclusive resource access, in parallel.

Usage

```rust extern crate shred;

use shred::{DispatcherBuilder, Read, Resource, ResourceId, System, SystemData, World, Write};

[derive(Debug, Default)]

struct ResA;

[derive(Debug, Default)]

struct ResB;

[derive(SystemData)] // Provided with shred-derive feature

struct Data<'a> { a: Read<'a, ResA>, b: Write<'a, ResB>, }

struct EmptySystem;

impl<'a> System<'a> for EmptySystem { type SystemData = Data<'a>;

fn run(&mut self, bundle: Data<'a>) {
    println!("{:?}", &*bundle.a);
    println!("{:?}", &*bundle.b);
}

}

fn main() { let mut world = World::empty(); let mut dispatcher = DispatcherBuilder::new() .with(EmptySystem, "empty", &[]) .build(); world.insert(ResA); world.insert(ResB);

dispatcher.dispatch(&mut world);

} ```

Please see the benchmark for a bigger (and useful) example.
