Trait for extracting entities from a planning solution.

This trait is implemented by closures/functions that can extract entity references from a solution of a specific type.

Required Methods

fn count(&self, solution: &dyn Any) -> Option<usize>

Returns the number of entities in the collection.

fn get<'a>(&self, solution: &'a dyn Any, index: usize) -> Option<&'a dyn Any>

Gets a reference to an entity by index.

fn get_mut<'a>( &self, solution: &'a mut dyn Any, index: usize, ) -> Option<&'a mut dyn Any>

Gets a mutable reference to an entity by index.

fn entity_refs(&self, solution: &dyn Any) -> Vec<EntityRef>

Returns an iterator over entity references.

fn clone_box(&self) -> Box<dyn EntityExtractor>

Clone this extractor.

fn clone_entity_boxed( &self, solution: &dyn Any, index: usize, ) -> Option<Box<dyn Any + Send + Sync>>

Clones an entity as a boxed value for insertion into the constraint session.

This is used for incremental scoring where entities need to be inserted into the BAVET session as owned, type-erased values.

fn entity_type_id(&self) -> TypeId

Returns the TypeId of the entity type.

Trait Implementations

impl Clone for Box<dyn EntityExtractor>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
