shred - Shared resource dispatcher
This library allows to dispatch systems, which can have interdependencies, shared and exclusive resource access, in parallel.
Usage
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.
