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.

moongraph is made up of two parts:

• The scheduler - provided by dagga
• The resource manager - provided by broomdog

Scheduling and running DAGs is a common problem and I didn't find any prior art.

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, a scrappy real-time renderer with advanced lighting
• Its scheduler is used for scheduling systems in apecs, a well-performing ECS with async integration.

This work will always be free and open source. If you use it (outright or for inspiration), please consider donating.
