Struct constellation::MapResource
[−]
[src]
pub struct MapResource<T: Any + Send + Sync> { /* fields omitted */ }
A MapResource stores per-entity data in a HashMap.
This entity resource is suitable for data which is only present for a small
portion of the total entities in the World.
Methods
impl<T: Any + Send + Sync> MapResource<T>[src]
fn new() -> MapResource<T>
Constructs a new MapResource.
fn add(&mut self, entity: Entity, component: T)
Adds entity data to the resource.
fn remove(&mut self, entity: Entity) -> Option<T>
Removes entity data from the resource.
Methods from Deref<Target = MapStorage<T>>
fn iter_components(&self) -> Values<Entity, T>
Gets an iterator over all entity data stored in the resource.
fn iter_components_mut(&mut self) -> ValuesMut<Entity, T>
Gets an iterator over all entity data stored in the resource.
fn iter(&self) -> Iter<Entity, T>
Gets an iterator over all entity data stored in the resource.
fn iter_mut(&mut self) -> IterMut<Entity, T>
Gets an iterator over all entity data stored in the resource.
