Contains metadata about:

• Entity types and their descriptors
• Problem fact types
• Score type

Fields

type_name: &'static str

Name of the solution type.

type_id: TypeId

TypeId of the solution type.

entity_descriptors: Vec<EntityDescriptor>

Descriptors for all entity types in this solution.

problem_fact_descriptors: Vec<ProblemFactDescriptor>

Descriptors for all problem fact types.

score_field: &'static str

Name of the score field.

score_is_optional: bool

Whether the score type is Option.

Implementations

impl SolutionDescriptor

pub fn new(type_name: &'static str, type_id: TypeId) -> Self

Creates a new SolutionDescriptor.

pub fn with_entity(self, descriptor: EntityDescriptor) -> Self

Adds an entity descriptor and indexes it by TypeId for O(1) lookup.

pub fn with_problem_fact(self, descriptor: ProblemFactDescriptor) -> Self

Adds a problem fact descriptor.

pub fn with_score_field(self, field: &'static str) -> Self

Sets the score field name.

pub fn find_entity_descriptor( &self, type_name: &str, ) -> Option<&EntityDescriptor>

Finds an entity descriptor by type name.

pub fn find_entity_descriptor_by_type( &self, type_id: TypeId, ) -> Option<&EntityDescriptor>

Finds an entity descriptor by type ID (O(1) lookup).

pub fn genuine_variable_descriptors(&self) -> Vec<&VariableDescriptor>

Returns all genuine variable descriptors across all entities.

pub fn shadow_variable_descriptors(&self) -> Vec<&VariableDescriptor>

Returns all shadow variable descriptors across all entities.

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

Returns the total number of entities across all entity collections.

Returns None if any entity descriptor lacks an extractor or the solution type doesn’t match.

pub fn all_entity_refs(&self, solution: &dyn Any) -> Vec<(usize, EntityRef)>

Returns all entity references across all entity collections.

pub fn for_each_entity<F>(&self, solution: &dyn Any, f: F)

where F: FnMut(usize, usize, &dyn Any),

Iterates over all entities in all collections.

The callback receives:

• The entity descriptor index
• The entity index within its collection
• A reference to the entity

pub fn get_entity<'a>( &self, solution: &'a dyn Any, descriptor_index: usize, entity_index: usize, ) -> Option<&'a dyn Any>

Gets an entity by descriptor index and entity index.

pub fn get_entity_mut<'a>( &self, solution: &'a mut dyn Any, descriptor_index: usize, entity_index: usize, ) -> Option<&'a mut dyn Any>

Gets a mutable entity by descriptor index and entity index.

pub fn entity_descriptor_count(&self) -> usize

Returns the number of entity descriptors.

pub fn problem_fact_descriptor_count(&self) -> usize

Returns the number of problem fact descriptors.

pub fn all_extractors_configured(&self) -> bool

Returns whether all entity descriptors have extractors configured.

Trait Implementations

impl Clone for SolutionDescriptor

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SolutionDescriptor

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

Formats the value using the given formatter.
