This library allows to dispatch systems, which can have interdependencies, shared and exclusive resource access, in parallel.
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.
1.65.0 stable
- lock-free
- no channels or similar functionality used (-> less overhead)
- allows both automated parallelization and fine-grained control
