Trait SpaceInteraction 

pub trait SpaceInteraction<A: PositionedAgent>: Space {
    type Error: Debug + Display;

    // Required methods
    fn random_position<R: RngCore>(&self, rng: &mut R) -> A::Position;
    fn add_agent(&mut self, agent: &A) -> Result<(), Self::Error>;
    fn remove_agent(&mut self, agent: &A) -> Result<(), Self::Error>;
    fn nearby_ids(&self, position: &A::Position, radius: usize) -> Vec<AgentId> ;
}

Trait that spaces implement to support agent lifecycle and neighbor queries.

Each space type defines its own Error type and provides methods to add/remove agents, generate random positions, and find nearby agent IDs.

Required Associated Types

type Error: Debug + Display

Error type for space operations.

Required Methods

fn random_position<R: RngCore>(&self, rng: &mut R) -> A::Position

Generate a random valid position within this space.

fn add_agent(&mut self, agent: &A) -> Result<(), Self::Error>

Register an agent with the space at its current position.

fn remove_agent(&mut self, agent: &A) -> Result<(), Self::Error>

Deregister an agent from the space.

fn nearby_ids(&self, position: &A::Position, radius: usize) -> Vec<AgentId>

Return all agent IDs within radius of position.

The meaning of radius depends on the space: grid cells (Chebyshev), Euclidean distance (continuous), or graph hops (graph).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
