# moongraph 🌙📈 `moongraph` is a Rust library for scheduling, managing resources, and running directed acyclic graphs. In `moongraph`, graph nodes are normal Rust functions and graph edges are function parameters and function results. The graph is built automatically by registering each function. `moongraph` figures out how the functions connect by their parameters and their results. `moongraph` validates and schedules nodes to run in parallel where possible, using `rayon` as the underlying parallelizing tech. This only happens when compiled with the "parallel" feature, on by default. ## what `moongraph` is made up of two parts: * The scheduler - provided by [`dagga`](https://github.com/schell/dagga) * The resource manager - provided by [`broomdog`](https://github.com/schell/broomdog) ## why Scheduling and running DAGs is a common problem and I didn't find any prior art. ## how [Read the introduction tutorial](https://docs.rs/moongraph/0.3.7/moongraph/tutorial/index.html) ## uses `moongraph` is in use in a number of other libraries (let me know if you use it in yours, and how :)) * As the render graph in [`renderling`](https://github.com/schell/renderling), a scrappy real-time renderer with advanced lighting * Its scheduler is used for scheduling systems in [`apecs`](https://github.com/schell/apecs), a well-performing ECS with async integration. ## 💚 Sponsor this!
