pub fn get_or_insert_with<F>(
&mut self,
type_id: ComponentTypeId,
create: F
) -> &mut dyn UnknownComponentStorage where
F: FnMut() -> Box<dyn UnknownComponentStorage>,
Gets or inserts the storage for the given component type.
sourcepub fn get(
&self,
type_id: ComponentTypeId
) -> Option<&dyn UnknownComponentStorage>
pub fn get(
&self,
type_id: ComponentTypeId
) -> Option<&dyn UnknownComponentStorage>
Returns the storage for the given component type.

&mut self,
type_id: ComponentTypeId
) -> Option<&mut dyn UnknownComponentStorage>
Returns the storage for the given component type.
sourcepub fn get_downcast_mut<T: Component>(&mut self) -> Option<&mut T::Storage>
pub fn get_downcast_mut<T: Component>(&mut self) -> Option<&mut T::Storage>
Returns the storage for the given component type.
sourcepub fn get_multi_mut(&mut self) -> MultiMut<'_>

impl<T> BorrowMut<T> for T where
T: ?Sized,
const: unstable · sourcepub fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

sourcepub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
pub 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. Read more
sourcepub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
pub 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. Read more
sourcepub fn as_any(&self) -> &(dyn Any + 'static)
pub 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. Read more
sourcepub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
pub 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. Read more
