Struct bevy::ecs::storage::SparseSets
pub struct SparseSets { /* private fields */ }
Expand description
A collection of ComponentSparseSet
storages, indexed by ComponentId
Can be accessed via Storages
Implementations§
§impl SparseSets
impl SparseSets
pub fn len(&self) -> usize
pub fn len(&self) -> usize
Returns the number of ComponentSparseSet
s this collection contains.
pub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true if this collection contains no ComponentSparseSet
s.
pub fn iter(&self) -> impl Iterator<Item = (ComponentId, &ComponentSparseSet)>
pub fn iter(&self) -> impl Iterator<Item = (ComponentId, &ComponentSparseSet)>
An Iterator visiting all (ComponentId
, ComponentSparseSet
) pairs.
NOTE: Order is not guaranteed.
pub fn get(&self, component_id: ComponentId) -> Option<&ComponentSparseSet>
pub fn get(&self, component_id: ComponentId) -> Option<&ComponentSparseSet>
Gets a reference to the ComponentSparseSet
of a ComponentId
.
