Create a newtype for equating petgraph graphs (use this if you want to #[derive(PartialEq)] but your struct has a petgraph::Graph field)


	#[derive(Debug, Clone, Serialize, Deserialize)]
	pub struct CustomGraph {
	pub graph: petgraph::Graph<MakelineNode, ()>,
	}

	impl PartialEq for CustomGraph {
	fn eq(&self, other: &Self) -> bool {
	graph_eq(&self.graph, &other.graph)
	}
