I'm using Petgraph's toposort function to get a sorted list of the graph's nodes. toposort does not however guarantee that all nodes at the same level will be returned in a consistent deterministic order. Is there some other option within Petgraph that will return the nodes in a deterministic order, or would I need to write my own function? (If so, any pointers?)
How can I get a deterministic topological sort in Petgraph?

So
toposort(and other algorithms) are sensitive to the order that graph nodes and edges are created. I had been feeding the graph with data from aHashMap, which cannot be iterated in a deterministic order. By switching my data to aBTreeMapthe nodes and edges are created in a reliable order, and then algorithms liketoposortgive deterministic results.
