Struct NearbyEntitySelector 

pub struct NearbyEntitySelector<S, M, ES> { /* private fields */ }

An entity selector that returns entities nearby to an origin entity.

The origin entity is obtained from a mimic recorder, allowing this selector to be synchronized with another selector that picks the “current” entity.

Zero-Erasure Design

The child entity selector ES is stored as a concrete generic type parameter, eliminating virtual dispatch overhead when iterating over candidate entities.

Implementations

impl<S, M, ES> NearbyEntitySelector<S, M, ES>

pub fn new( child: ES, origin_recorder: MimicRecorder, distance_meter: M, config: NearbySelectionConfig, ) -> Self

Creates a new nearby entity selector.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S, M, ES> EntitySelector<S> for NearbyEntitySelector<S, M, ES>

where S: PlanningSolution, M: DynDistanceMeter + 'static, ES: EntitySelector<S>,

fn iter<'a, D: ScoreDirector<S>>( &'a self, score_director: &'a D, ) -> Box<dyn Iterator<Item = EntityReference> + 'a>

Returns an iterator over entity references.

fn size<D: ScoreDirector<S>>(&self, score_director: &D) -> usize

Returns the approximate number of entities.

fn is_never_ending(&self) -> bool

Returns true if this selector may return the same entity multiple times.
