Crate rustsim_spaces 

Space implementations for agent-based models.

Each space defines a topology in which agents exist and provides:

• Position types
• Agent registration / deregistration
• Neighbor queries
• Random position generation

Space	Position type	Metric	Use case
NothingSpace	-	-	Non-spatial models
Grid2D	(usize, usize)	Chebyshev	Cellular automata, Schelling
Grid2DSingle	(usize, usize)	Chebyshev	Single-occupancy grids
ContinuousSpace2D	ContinuousPos	Euclidean	2D flocking, particles
ContinuousSpace3D	ContinuousPos3D	Euclidean	3D physics
GraphSpace	usize (node index)	Hops (BFS)	Networks, social graphs
HybridSpace	HybridPos	Hops + Euclidean	Buildings, multi-room environments
LinkSpace	(NodeId, NodeId)	Link distance	Generic link-based networks
