Struct PropertyStore 

pub struct PropertyStore<E: Entity> { /* private fields */ }

A wrapper around a vector of property value stores.

Implementations

impl<E: Entity> PropertyStore<E>

pub fn new() -> Self

Creates a new PropertyStore.

pub fn get<P: Property<E>>(&self) -> &PropertyValueStoreCore<E, P>

Fetches an immutable reference to the PropertyValueStoreCore<E, P>.

pub fn get_mut<P: Property<E>>(&mut self) -> &mut PropertyValueStoreCore<E, P>

Fetches a mutable reference to the PropertyValueStoreCore<E, P>.

pub fn set_property_indexed<P: Property<E>>( &mut self, index_type: PropertyIndexType, )

Sets the index type for P. Passing PropertyIndexType::Unindexed removes any existing index for P.

Note that the index might not live in the PropertyValueStore associated with P itself, as in the case of multi-properties which share a single index among all equivalent multi-properties.

pub fn create_value_change_counter<PL, P>(&mut self) -> usize

where PL: PropertyList<E> + Eq + Hash, P: Property<E> + Eq + Hash,

Creates a stratified value change counter for tracked property P with strata PL.

Returns the counter ID.

pub fn index_unindexed_entities_for_property_id( &mut self, context: &Context, property_id: usize, )

Updates the index of the property having the given ID for any entities that have been added to the context since the last time the index was updated.

pub fn index_unindexed_entities_for_all_properties(&mut self, context: &Context)

Updates all indexed properties for any entities that have been added since the last update.

pub fn get_index_set_with_hash_for_property_id( &self, property_id: usize, hash: HashValueType, ) -> IndexSetResult<'_, E>

pub fn get_index_count_with_hash_for_property_id( &self, property_id: usize, hash: HashValueType, ) -> IndexCountResult

Trait Implementations

impl<E: Entity> Default for PropertyStore<E>

fn default() -> Self

Returns the “default value” for a type.
