Struct bevy_ecs::storage::SparseSets  
source · pub struct SparseSets { /* private fields */ }Expand description
A collection of ComponentSparseSet storages, indexed by ComponentId
Can be accessed via Storages
Implementations§
source§impl SparseSets
 
impl SparseSets
sourcepub fn len(&self) -> usize
 
pub fn len(&self) -> usize
Returns the number of ComponentSparseSets this collection contains.
sourcepub fn is_empty(&self) -> bool
 
pub fn is_empty(&self) -> bool
Returns true if this collection contains no ComponentSparseSets.
sourcepub 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.
sourcepub 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.

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
Convert 
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
 
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
Convert 
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.source§fn as_any(&self) -> &(dyn Any + 'static)
 
fn as_any(&self) -> &(dyn Any + 'static)
Convert 
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.source§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
 
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert 
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.source§impl<T> FromWorld for Twhere
