Expand description

Trait for selecting entities from a planning solution.

Entity selectors provide an iteration order over the entities that the solver will consider for moves.

Required Methods§

Source

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

Returns an iterator over entity references.

The iterator yields EntityReference values that identify entities within the solution.

Source

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

Returns the approximate number of entities.

Provided Methods§

Source

fn is_never_ending(&self) -> bool

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