Struct EntityOrientedDenseMap

pub struct EntityOrientedDenseMap<K: EntityOrientedMapKey<V>, V> { /* private fields */ }

Map with K keys and V values, that is:

• “entity-oriented” K keys, i.e. that are or contain exactly one entity (supported via K: EntityOrientedMapKey<V> for extensibility)
• “dense” in the sense of few (or no) gaps in (the entities in) its keys (relative to the entities defined in the corresponding EntityDefs)

By design there is no way to iterate the entries in an EntityOrientedDenseMap.

Trait Implementations

impl<K: Clone + EntityOrientedMapKey<V>, V: Clone> Clone for EntityOrientedDenseMap<K, V>

where K::Entity: Clone, K::DenseValueSlots: Clone,

fn clone(&self) -> EntityOrientedDenseMap<K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K: EntityOrientedMapKey<V>, V> Default for EntityOrientedDenseMap<K, V>

fn default() -> Self

Returns the “default value” for a type.

impl<K: EntityOrientedMapKey<V>, V> Index<K> for EntityOrientedDenseMap<K, V>

type Output = V

The returned type after indexing.

fn index(&self, key: K) -> &V

Performs the indexing (container[index]) operation.
