Trait NeighborSensing

pub trait NeighborSensing<Pos, Acc, Inf = ()>: InteractionInformation<Inf> {
    // Required methods
    fn accumulate_information(
        &self,
        own_pos: &Pos,
        ext_pos: &Pos,
        ext_inf: &Inf,
        accumulator: &mut Acc,
    ) -> Result<(), CalcError>;
    fn react_to_neighbors(&mut self, accumulator: &Acc) -> Result<(), CalcError>;
    fn clear_accumulator(accumulator: &mut Acc);
}

Available on crate feature cara only.

Allows reacting to multiple neighbors

Information of neighbors is first accumulated via the NeighborSensing::accumulate_information function and finally, the cell reacts to the gathered data via the NeighborSensing::react_to_neighbors function. Finally, the accumulator is cleared with NeighborSensing::clear_accumulator.

Neighbor Counting

struct Cell {/* .. */};

impl<Pos, Inf> NeighborSensing<Pos, usize, Inf> for Cell
where
    Cell: InteractionInformation<Inf>,
{
    fn accumulate_information(
        &self,
        _: &Pos,
        _: &Pos,
        _: &Inf,
        neighbors: &mut usize
    ) -> Result<(), CalcError> {
        Ok(*neighbors += 1)
    }

    fn react_to_neighbors(&mut self, neighbors: &usize) -> Result<(), CalcError> {
        /* .. */
        Ok(())
    }

    fn clear_accumulator(neighbors: &mut usize) {
        *neighbors = 0;
    }
}

Required Methods

fn accumulate_information( &self, own_pos: &Pos, ext_pos: &Pos, ext_inf: &Inf, accumulator: &mut Acc, ) -> Result<(), CalcError>

Checks if the other cell represented by position and information is a neighbor to the current one or not.

fn react_to_neighbors(&mut self, accumulator: &Acc) -> Result<(), CalcError>

Reacts to the results gathered by the [Interaction::is_neighbor] method and changes the state of the cell.

fn clear_accumulator(accumulator: &mut Acc)

Clears the accumulator

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.
