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 index_unindexed_entities_for_property_id( &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. As a convenience, returns false if this property is not indexed, true otherwise.

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

pub fn get_index_count_with_hash_for_property_id( &self, context: &Context, 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.
